Adding a document to a collections keeps hanging - firebase

Disclaimer: I'm new to React Native and Firebase in general, so this might be me just being dumb. Anyways, I'm trying to learn something new and making a test app at the same time and I've run into an issue when registering users.
I have an action that I dispatch that should be able to Authenticate users and at the same time add the user.uid and email to a collection called users.
The problem is that every time that I call the await to add the user the app just hangs there and nothing happens. I tried to resolve the Promise or catch an error and it still gives me nothing.
Here's the full action:
export const registerUser =
(
email: string,
password: string,
): ThunkAction<void, RootState, unknown, SignUpTypes> =>
async (dispatch: Dispatch<SignUpTypes>) => {
dispatch({ type: SIGN_UP });
try {
const response = await firebase
.auth()
.createUserWithEmailAndPassword(email, password);
const { user, additionalUserInfo } = response;
const userProfile = {
uid: user?.uid,
email,
};
await usersCollection
.doc(user?.uid)
.set(userProfile)
.then(res => console.log('res', res))
.catch(error => console.log('error', error));
dispatch({
type: SIGN_UP_COMPLETE,
payload: {
isLoggedIn: true,
user: userProfile,
isNewUser: additionalUserInfo?.isNewUser,
},
});
} catch (error) {
dispatch({
type: SIGN_UP_ERROR,
payload: { error: { code: error.code, message: error.message } },
});
}
};
I got nothing from the moment that I call the await on the usersCollection, not even a console log and everything just freezes there. Not sure if it's something related to thunks but or not.
Also, it if helps I'm always having this warning:
Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info
Any ideas on what am I missing?
Thanks ✌

Don't combine await and then. To get your logs try this:
try {
const res = await usersCollection
.doc(user?.uid)
.set(userProfile)
console.log('res', res)
}
catch(e){
console.log('e', e)
}

Signin method with Nextjs and trpc returning resolver is not a function

So im trying to build my register method without re-enventing nothing crazy with the create-t3-app stack with nextjs, trpc and nextauth:
export const signUpRouter = router({
signup: publicProcedure.input(UserModel).mutation(async ({ ctx, input }) => {
debugger;
try {
const { nickname, email, password } = input;
//check duplicate users
const checkingUsers = await ctx.prisma.user.findFirst({
where: {
email,
},
});
if (checkingUsers) {
return { message: "User already exists..." };
}
//hash password
return await ctx.prisma.user.create({
data: {
nickname,
email,
password: await hash(password, 12),
},
});
} catch (error: any) {
console.log("error", error);
throw new Error(error);
}
}),
});
export default signUpRouter;
This file is inside pages/api/auth/signup.ts
Should I have this on the server part ?
I have the router on my appRouter file
export const appRouter = router({
userLogin: userLoginRouter,
auth: authRouter,
signin: signInRouter,
signup: signUpRouter,
});
And when clicking on the register button:
async function onSumitRegisterValues(values: any) {
const options = {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(values),
};
await fetch("http://localhost:3000/api/auth/signup", options)
.then((res) => res.json())
.then((data) => {
if (data?.ok) router.push("http://localhost:3000");
});
}
The values form contains nickname, email, password and cpassword to confirm password.
im getting a 500 on post
Server Error
TypeError: resolver is not a function
This error happened while generating the page. Any console logs will be displayed in the terminal window.
Maybe its my lack of knowledge with trpc and next but ngl, its making me want to separate my backend into something different. But since im not rushing in building this project i really want to try to figure out what i shoud be doing better.
Why are you using fetch instead of using your useQuery method from trpc? The whole point of trpc is that you can skip fetch and will also have type safety.

Next JS User session data successfully saves locally, but fails to save when deployed to AWS

In an app I'm building, a user logins in (validates through Magic Auth), and we save the user data in the session variable (using Iron for session management):
export default withSessionRoute(async (req, res) => {
try {
const didToken = req.headers?.authorization?.substr(7);
if (didToken) {
magic.token.validate(didToken);
const metadata: any = await magic.users.getMetadataByToken(didToken);
const response = await createUser({ email: metadata.email });
req.session.user = response.data.user;
req.session.userMetadata = metadata;
await req.session.save();
return res.send({ user: response.data.user, authenticated: true });
} else {
res.status(200).json({ authenticated: false });
}
} catch (error: any) {
console.log(error);
res.status(500).json({ error: error.message });
}
});
This works totally fine locally (req.session.user remains filled with user data), but for some reason on my deployed app, it does not work at all. It still returns the user data in "req.send", but the session variable is empty, so it does not seem to have saved.
Any ideas on what the issue could be?

Vue Axios Interceptor Response Firebase 401 Token Expired/Refresh (undefined)

I'm using the following interceptors in a Vuejs v2 website to push a firebase token to my node backend. There in the backend, I detect/verify the token, pull some data using the uid from a database and then process any api calls.
Even though I am using the firebase onIdTokenChanged to automatically retrieve new ID tokens, sometimes, if the user is logged in, yet inactive for an hour, the token expires without refreshing. Now, this isn't a huge deal - I could check in the axios response interceptor and push them to a login page, but that seems annoying, if I can detect a 401 token expired, resend the axios call and have a refreshed token, the user won't even know it happened if they happen to interact with a component that requires data from an API call. So here is what I have:
main.js
Vue.prototype.$axios.interceptors.request.use(function (config) {
const token = store.getters.getSessionToken;
config.headers.Authorization = `Bearer ${token}`;
return config;
});
Vue.prototype.$axios.interceptors.response.use((response) => {
return response }, async function (error) {
let originalRequest = error.config
if (error.response.status === 401 && !originalRequest._retry) {
originalRequest._retry = true;
let user = auth.currentUser;
await store.dispatch("setUser", {user: user, refresh: true}).then(() => {
const token = store.getters.getSessionToken;
Vue.prototype.$axios.defaults.headers.common['Authorization'] = 'Bearer ' + token;
return Vue.prototype.$axios.request(originalRequest);
});
}
return Promise.reject(error); });
let app;
auth.onAuthStateChanged(async user => {
await store.dispatch("setUser", {user: user, refresh: false}).then(() => {
if (!app) {
app = new Vue({
router,
store,
vuetify,
render: h => h(App)
}).$mount('#app')
}
})
.catch(error => {
console.log(error);
});
});
vuex
setUser({dispatch, commit}, {user, refresh}) {
return new Promise((resolve) => {
if(user)
{
user.getIdToken(refresh).then(token => {
commit('SET_SESSION_TOKEN', token);
this._vm.$axios.get('/api/user/session').then((response) => {
if(response.status === 200) {
commit('SET_SESSION_USER', response.data);
resolve(response);
}
})
.catch(error => {
dispatch('logout');
dispatch('setSnackbar', {
color: "error",
timeout: 4000,
text: 'Server unavailable: '+error
});
resolve();
});
})
.catch(error => {
dispatch('logout');
dispatch('setSnackbar', {
color: "error",
timeout: 4000,
text: 'Unable to verify auth token.'+error
});
resolve();
});
}
else
{
console.log('running logout');
commit('SET_SESSION_USER', null);
commit('SET_SESSION_TOKEN', null);
resolve();
}
})
},
I am setting the token in vuex and then using it in the interceptors for all API calls. So the issue I am seeing with this code is, I'm making an API call with an expired token to the backend. This returns a 401 and the axios response interceptor picks it up and goes through the process of refreshing the firebase token. This then makes a new API call with the same config as the original to the backend with the updated token and returns it to the original API call (below).
This all seems to work, and I can see in dev tools/network, the response from the API call is sending back the correct data. However, it seems to be falling into the catch of the following api call/code. I get an "undefined" when trying to load the form field with response.data.server, for example. This page loads everything normally if I refresh the page (again, as it should with the normal token/loading process), so I know there aren't loading issues.
vue component (loads smtp settings into the page)
getSMTPSettings: async function() {
await this.$axios.get('/api/smtp')
.then((response) => {
this.form.server = response.data.server;
this.form.port = response.data.port;
this.form.authemail = response.data.authemail;
this.form.authpassword = response.data.authpassword;
this.form.sendemail = response.data.sendemail;
this.form.testemail = response.data.testemail;
this.form.protocol = response.data.protocol;
})
.catch(error => {
console.log(error);
});
},
I have been looking at this for a few days and I can't figure out why it won't load it. The data seems to be there. Is the timing of what I'm doing causing me issues? It doesn't appear to be a CORS problem, I am not getting any errors there.
Your main issue is mixing async / await with .then(). Your response interceptor isn't returning the next response because you've wrapped that part in then() without returning the outer promise.
Keep things simple with async / await everywhere.
Also, setting common headers defeats the point in using interceptors. You've already got a request interceptor, let it do its job
// wait for this to complete
await store.dispatch("setUser", { user, refresh: true })
// your token is now in the store and can be used by the request interceptor
// re-run the original request
return Vue.prototype.$axios.request(originalRequest)
Your store action also falls into the explicit promise construction antipattern and can be simplified
async setUser({ dispatch, commit }, { user, refresh }) {
if(user) {
try {
const token = await user.getIdToken(refresh);
commit('SET_SESSION_TOKEN', token);
try {
const { data } = await this._vm.$axios.get('/api/user/session');
commit('SET_SESSION_USER', data);
} catch (err) {
dispatch('logout');
dispatch('setSnackbar', {
color: "error",
timeout: 4000,
text: `Server unavailable: ${err.response?.data ?? err.message}`
})
}
} catch (err) {
dispatch('logout');
dispatch('setSnackbar', {
color: "error",
timeout: 4000,
text: `Unable to verify auth token. ${error}`
})
}
} else {
console.log('running logout');
commit('SET_SESSION_USER', null);
commit('SET_SESSION_TOKEN', null);
}
}

Firebase functions cloud messaging notification not being recieved

When I send a notification from the Firebase cloud messaging console, my device receives it without a problem, but when I send it via a cloud functions, the function log says it was successfully sent but my device does not receive it. I tried switching to type script, sending the notification with different conditions but nothing works. The app is written in flutter.
My function code:
exports.sendNotification = functions.https.onRequest((request, response) => {
const db = admin.firestore();
const fcm = admin.messaging();
db.collection("users")
.where("bananas", "==", 1666).get().then(
(result) => {
if (result.size > 0) {
result.forEach((doc) => {
const payload = {
token: doc.data().NotToken,
notification: {
title: "iam a notification",
body: "Yay",
icon: "https://cdn1.iconfinder.com/data/icons/logos-brands-in-colors/231/among-us-player-white-512.png",
},
};
fcm.send(payload).then((response) => {
// Response is a message ID string.
console.log("Successfully sent message: "+
doc.data().NotToken+ " ", response);
return {success: true};
}).catch((error) => {
return {error: error.code};
});
});
}
});
response.send("Notification sent !");
functions.logger.info("Notification sent!");
return null;
});
cloud log
Any ideas?
Did you notice how your code never logs this message?
Successfully sent message
That's because both loading from Firestore, and sending messaging through Cloud Messaging are asynchronous calls. So your response.send("Notification sent !") runs before the data is ever retrieved from the database, and Cloud Functions at that point terminates your code to prevent charging after you say that you are done.
If you have asynchronous operations in your code, you need to return a promise from the top-level of your code that resolves/rejects when all asynchronous code has completed. So in your case that means the promise should only resolve once you've loaded the data from Firestore, and sent the messages.
Let's start with a simple example. Say that you want to only send a single message, no matter how many documents are in the database.
exports.sendNotification = functions.https.onRequest((request, response) => {
const db = admin.firestore();
const fcm = admin.messaging();
return db.collection("users") // 👈 Add return here
.where("bananas", "==", 1666).get().then((result) => {
if (result.size > 0) {
const doc = result.docs[0]; // 👈 Get the first result
const payload = {
token: doc.data().NotToken,
notification: {
title: "iam a notification",
body: "Yay",
icon: "https://cdn1.iconfinder.com/data/icons/logos-brands-in-colors/231/among-us-player-white-512.png",
},
};
return fcm.send(payload).then((response) => { // 👈 Add return here
console.log("Successfully sent message: "+
doc.data().NotToken+ " ", response);
response.send("Notification sent !"); // 👈 Move this call here
return {success: true};
}).catch((error) => {
// TODO: Send an error back to the caller
return {error: error.code};
});
}
});
});
So the top-level code now returns the result from loading data from Firestore, and in there, we return the call from calling FCM, which then in turn returns return {success: true};. When returning promises, the results bubble up - so you can typically just keep returning the nested results.
You'll also not that we've moved the response.send into the code that runs after calling FCM, as we don't want to send a result back to the caller until the FCM call is done.
The above is the simple variant, because in reality you have multiple documents, and you are only done once all of them are done.
For that we are going to use Promise.all(), which takes an array of promises and resolves once all those promises resolve. So we're going to capture all the calls to FCM (which returns a promise) and collection them in an array, that we then pass to Promise.all().
exports.sendNotification = functions.https.onRequest((request, response) => {
const db = admin.firestore();
const fcm = admin.messaging();
return db.collection("users")
.where("bananas", "==", 1666).get().then((result) => {
if (result.size > 0) {
let promises = [];
result.forEach((doc) => {
const payload = {
token: doc.data().NotToken,
notification: {
title: "iam a notification",
body: "Yay",
icon: "https://cdn1.iconfinder.com/data/icons/logos-brands-in-colors/231/among-us-player-white-512.png",
},
};
promises.push(fcm.send(payload))
});
return Promise.al(promises).then((results) => {
console.log("Successfully sent messages");
response.send("Notification sent !");
return {success: true};
});
}
});
});
While this may be a lot to grok all at once, handling asynchronous behavior is quite well covered in the Firebase documentation on terminating functions, in this video series on Learn JavaScript Promises with Cloud Functions, and in quite a few tutorials out there - so I recommend spending some time on those to get to grips with asynchronous code.

Firebase functions just dying out with no explanation or error

I'm trying to implement a messaging application using Firebase Firestore and Firebase Cloud Functions.
In essence, chat messages are stored as individual documents in a subcollection. At first, I implemented this as directly adding a document from the client and listening on the collection and updating the clients when a change happens but later I decided to switch to using Cloud functions so that I can add some functionality that's better done on the server side(filtering etc.).
So I created a function for sending messages, which creates the documents on behalf of the users when the users call the function from the app(i.e. tap the send button).
The function worked and I was able to monitor the processes through the logs. Unfortunately, the functions began to die out without error, the console was reporting that the functions are executed successfully and it usually took less than a second to execute.
I suspect that it has something to do with the promises that probably continue to run but this is the same code that was working but failing today.
If I try a few more times, the functions seem to be working again. Do I need to keep the functions "warm"? Are cloud functions not reliable enough to handle this kind of tasks? When I say my user that a message is sent, I need to be able to confirm that it is sent and communicate it with the users if it failed.
It's hard to debug the issue because no errors are thrown(not even info message, it's just as if didn't happen), it just says that the function successfully finished execution and nothing happened.
Am I missing something here? Thank you.
exports.sendMessage = functions.https.onCall((data, context) => {
if (context.auth.uid == undefined) {
console.warn("SEND MESSAGE: USER NOT SIGNED IN");
return;
}
console.log("Sending message:", data)
const matchId = data["matchId"];
const message = data["message"]
const uid = context.auth.uid
admin.firestore().collection(MatchingUsers).doc(matchId).collection(UserMessages).add({
type: "text",
from: uid,
message: message,
timestamp: admin.firestore.Timestamp.now()
}).then(result => {
console.log("Message sent")
}).catch(err => {
console.log("Error sending mesage:", err)
})
})
As explained in the documentation of the HTTP Callable Cloud Functions:
To return data after an asynchronous operation, return a promise.
Then follows an example:
const sanitizedMessage = sanitizer.sanitizeText(text); // Sanitize the message.
return admin.database().ref('/messages').push({
text: sanitizedMessage,
author: { uid, name, picture, email },
}).then(() => {
console.log('New Message written');
// Returning the sanitized message to the client.
return { text: sanitizedMessage };
})
So you need to adapt your code as follows:
exports.sendMessage = functions.https.onCall((data, context) => {
if (context.auth.uid == undefined) {
console.warn("SEND MESSAGE: USER NOT SIGNED IN");
//Here send back an error as explained here: https://firebase.google.com/docs/functions/callable#handle_errors
}
console.log("Sending message:", data)
const matchId = data["matchId"];
const message = data["message"]
const uid = context.auth.uid
//Note the return on next line
return admin.firestore().collection(MatchingUsers).doc(matchId).collection(UserMessages).add({
type: "text",
from: uid,
message: message,
timestamp: admin.firestore.Timestamp.now()
}).then(result => {
console.log("Message sent");
return { text: "Message sent" };
}).catch(err => {
console.log("Error sending mesage:", err);
//Here, again, send back an error as explained here: https://firebase.google.com/docs/functions/callable#handle_errors
})
})
If you don't want to return a value to the client, you could do as follows, returning null when the Promise returned by the add() asynchronous method resolves. (Not tested but it should work).
exports.sendMessage = functions.https.onCall((data, context) => {
if (context.auth.uid == undefined) {
console.warn("SEND MESSAGE: USER NOT SIGNED IN");
return null;
}
console.log("Sending message:", data)
const matchId = data["matchId"];
const message = data["message"]
const uid = context.auth.uid
//Note the return on next line
return admin.firestore().collection(MatchingUsers).doc(matchId).collection(UserMessages).add({
type: "text",
from: uid,
message: message,
timestamp: admin.firestore.Timestamp.now()
}).then(result => {
console.log("Message sent"); //Actually, if you don't need this console.log() you can remove this entire then() block, returning the promise from add() is enough
return null;
}).catch(err => {
console.log("Error sending mesage:", err);
return null;
})
})
