When using Firestore in Cloud Functions, how to use the Create a missing index through an error message feature?
Basically, after I use a new Firestore query in my Cloud Function, where should I expect to find the "error message [that] includes a direct link to create the missing index"?
Update: add sample code based on a comment suggestion
Assume the query below wasn't used before. After I deploy the function to Cloud Functions and use it, where can I find the automatically-created link for creating the missing index?
import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';
admin.initializeApp(functions.config().firebase);
const db = admin.firestore();
export const posts = functions.https.onCall(async (
data: { uid: string },
context
) => {
// ...
const querySnapshot = await postsRef
.where('uid', '==', data.uid)
.orderBy('timestamp', 'desc')
.get();
// ...
});
When you perform the query, the resulting promise will become rejected. Your code will need to catch that error from the rejected promise, then log the error object. The url will be in the log message. (I'm assuming you're using node here, but the same error handling will apply to any language using its conventions for capturing and logging errors.)

I was trying to do pagination with firebase and nuxt js . When trying to read from firestore using the fetch hook I get an error (Maximum call stack size exceeded ). It is worth noting that when doing this same process with the hook mounted works perfectly. I need to use the fetch hook for ssr. I think the error comes from assigning the value to the variable lastDoc which I need to save the cursor that I will later use in the pagination.
Here is the code
async fetch() {
let queryShows = query(
collection(db, "shows"),
orderBy("ano", "desc"),
orderBy("nombre", "asc"),
limit(3)
);
const querySnapshotShows = await getDocs(queryShows);
this.lastDoc = querySnapshotShows.docs[querySnapshotShows.docs.length - 1]; //Don't know why this cause an error
querySnapshotShows.forEach((doc) => {
this.shows.push({ id: doc.id, ...doc.data() });
});}
Here is the error

I have very simple cloud function truggers firestore document onCreate, when i deploy this function I'm getting Error
Functions deploy had errors with the following functions:
makeUppercase
In cloud logs
ERROR: error fetching storage source: generic::unknown: retry budget exhausted (3 attempts): fetching gcs source: unpacking source from gcs: source fetch container exited with non-zero status: 1
My function .ts
import * as functions from "firebase-functions";
exports.makeUppercase = functions.firestore.document("/clients/{documentId}")
.onCreate((snap, context) => {
// Grab the current value of what was written to Firestore.
const original = snap.data().original;
functions.logger.log("Uppercasing", context.params.documentId, original);
const uppercase = original.toUpperCase();
return snap.ref.set({uppercase}, {merge: true});
});
Also please check my firestore
In package JSON node version is 14. I don't know what went wrong, I have been trying this couple of hours and always same Error.
I've tried out the export data from Firebase to 'backup' my database but much to my surprise it didn't export the sub-collections, despite them being uniquely named. Is there a way to export the entire database?
I know there are NPM packages that can do this but it doesn't export to the binary format that the GCP exports to which is more space efficient.
EDIT:
I've tried to export the data via the scheduled cloud function and the GCP console. I followed the instructions exactly and didn't change anything.
They both uploaded a folder with the contents in the images below.
The root directory:
all_namespaces/all_kinds
I imported the 2020-11-05T14:40:04_75653.overall_export_metadata via the GCP console and sure enough all the top level collections and documents came back, but all the sub-collections were not there. I expected that all the collections and subcollections would be restored from the import.
So in summary I tried to export the data via two methods and upload via one.
Here's the scheduled cloud function:
const functions = require('firebase-functions');
const firestore = require('#google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
// Replace BUCKET_NAME
const bucket = 'gs://BUCKET_NAME';
exports.scheduledFirestoreExport = functions.pubsub
.schedule('every 24 hours')
.onRun((context) => {
const projectId = process.env.GCP_PROJECT || process.env.GCLOUD_PROJECT;
const databaseName =
client.databasePath(projectId, '(default)');
return client.exportDocuments({
name: databaseName,
outputUriPrefix: bucket,
// Leave collectionIds empty to export all collections
// or set to a list of collection IDs to export,
// collectionIds: ['users', 'posts']
collectionIds: []
})
.then(responses => {
const response = responses[0];
console.log(`Operation Name: ${response['name']}`);
})
.catch(err => {
console.error(err);
throw new Error('Export operation failed');
});
});
So with the above code, I'd expect it to export everything in firestore. For example if I had the sub-collection:
orders/{order}/items
I'd expect that when I import the data via the GCP console, I get back the sub-collection listed above. However, I only get back the top-level. i.e.
orders/{order}
** This is that my firestore (emulator) looks like**
I am trying to practice learning about cloud functions with firebase emulator however, I am running into this probably more often than I expected. I hope it is my end's problem.
I am trying to write a function where when the user made the https request to create an order, the background trigger function will return out the total (quantity * price) to the user. The later part is still WIP at the moment; I am currently just trying to understand and learn more about cloud functions.
This is the https request code I have to add the item, price, and quantity to my firestore. It works well and as intended.
exports.addCurrentOrder = functions.https.onRequest(async (req, res) => {
const useruid = req.query.uid;
const itemName = req.query.itemName;
const itemPrice = req.query.itemPrice;
const itemQuantity = req.query.itemQuantity;
console.log('This is in useruid: ', useruid);
const data = { [useruid] : {
'Item Name': itemName,
'Item Price': itemPrice,
'Item Quantity': itemQuantity,
}};
const writeResult = await admin.firestore().collection('Current Orders').add(data);
res.json({result: data});
});
This is the part that's giving me all sorts of errors:
exports.getTotal = functions.firestore.document('Current Orders/{documentId}').onCreate((snap, context) => {
const data = snap.data();
for(const i in data){
console.log('This is in i: ', i);
}
return snap.ref.set({'testing': 'testing'}, {merge: true});
});
Whenever I have this, the console will always give me:

⚠ Your function was killed because it raised an unhandled error.
Even if I comment out the function that I think is giving me the error, I will still run into this problem (and when I run the sample function found on the official cloud function guide too!)
I know there is definitely something that I am doing horribly wrong on the background trigger (and would love to have someone be kind enough to show me how to write such function/get me startted)
What am I doing wrong here? Or is this some sort of the emulator bug?
I think I found it. Although I think there is better solution possible.
On completely new system+firebase I have used this firebase emulators tutorial to create first onCreate trigger called makeUppercase and it worked. Than I added your getTotal and it was not working and as well it spoiled the makeUppercase trigger as well!
I started to test some changes. Tried many times and, finally, I have removed "space" character from collection name like this:
exports.getTotal = functions.firestore.document('CurrentOrders/{documentId}')...etc.
Both triggers started working as well (used fresh VM with Windows+node12). It's possible that it will be working on real Firestore instance. So it seems the "space" in collection name is generating some errors in whole index.js.
Follow the guide of using Cloud Functions with Firebase.
Setup environment
setup project in Firebase
Created function
command prompt writes that function deployed, but firebase is empty.
I am new with deploying functions so I am sure that it is stupid question and I think I did something wrong in setting up but I checked three times different guides and it looks everything done right. So please if you know what the problem it is can be?
I used this guide and there I done everything till initializing the project
https://firebase.google.com/docs/functions/get-started
After that in index.js I wrote a function
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(function.config().firebase);
export.sendNotification = functions.database
.ref('/notifications/{user_id}/{notification_id}')
.onWrite(event => {
conts user_id = event.params.user_id;
const notification = event.params.notification_id;
if(!event.data.val()){
return console.log('A notification has been deleted ', notification_id);
}
const payload = {
notification: {
title: "Friend Request",
body: "Received new Friend Request",
icon: "default"
}
};
return admin.messaging().sendToDevice(/*Token*/, payload).then(response =>{
console.log('');
});
});
And with the command
firebase deploy
I tried to deploy function
But in firebase cattegory "Function" it is still empty
Error in CMD
There is syntax error, Please change below line in your code
admin.initializeApp(function.config().firebase);
to
admin.initializeApp(functions.config().firebase);
I'm quite late here but it might help somebody else. You're right, it is typo. The correct command is:
exports
not
export
