I have one application in which user can login and see some info.
Issue:
user able to login and see info and logout any number of times before changing network.but once user change network(from wifi to mobile or vice versa) and try to login and fetch information. it's throwing error:Network request failed at XMLHttpRequest.xhr.onerror (fetch.js:441)
Note: i am using fetch api for network call.
Fetch Api call:
export const request = async function request(path, body = null, method = 'GET') {
try {
const headers = {
'Content-Type': body instanceof FormData ? 'multipart/form-data' : 'application/json',
};
const token = await AsyncStorage.getItem('authToken');
if (token) {
headers.Authorization = token;
}
const config = {
method,
url: Config.API_URL + path,
headers,
};
if (!['HEAD', 'GET'].includes(method.toUpperCase())) {
config.body = body instanceof FormData ? body : JSON.stringify(body);
}
const response = await fetch(Config.API_URL + path, config);
const data = await response.json();
if (response.status >= 400) {
throw data.error;
}
return data;
} catch (e) {
console.log('Error', path, e);
return Promise.reject(e);
}

The code for the bot is currently hosted on a Cloudflare worker, and there are no errors being reported from that end. Additionally, upon investigation of the Botfather side, everything seems to be functioning normally as well. However, despite attempting various solutions such as changing bots, tokens, and chat groups, the issue remains.
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request))
})
async function handleRequest(request) {
const { pathname } = new URL(request.url)
if (pathname === '/') {
return new Response('Hello! This is a Telegram bot. Send me a message.')
}
const { text } = await request.json()
if (text.startsWith('/start')) {
return new Response('Welcome to the bot! Use the /help command to see available options.')
} else if (text.startsWith('/help')) {
return new Response('Available commands:\n/scrape - scrapes videos from the specified website and sends them to the Telegram chat.\n/<example> - scrapes posts from the specified website and sends them to the Telegram chat.')
} else if (text.startsWith('/scrape')) {
const videoUrl = await scrapeVideoUrl('<example url>')
const message = `Here's the latest video: ${videoUrl}`
await sendMessageToChatId(message)
return new Response('OK')
} else if (text.startsWith('/<example>')) {
const post = await scrapePost('<example url>')
const message = `Here's the latest post: ${post.title}\n${post.url}`
await sendMessageToChatId(message)
return new Response('OK')
} else {
return new Response('Invalid command. Use the /help command to see available options.')
}
}
async function scrapeVideoUrl(url) {
const response = await fetch(url)
const html = await response.text()
const cheerio = require('cheerio')
const $ = cheerio.load(html)
const videoUrl = $('div.media > a').attr('href')
return videoUrl
}
async function scrapePost(url) {
const response = await fetch(url)
const html = await response.text()
const cheerio = require('cheerio')
const $ = cheerio.load(html)
const post = {
title: $('div.content h1').text(),
url: url
}
return post
}
async function sendMessageToChatId(message) {
const telegramApiUrl = "https://api.telegram.org/bot<token>/sendMessage";
const chatId = "<id>";
const response = await fetch(telegramApiUrl, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
chat_id: chatId,
text: message
})
})
}
There is zero response on the telegram side, even doe on web side everything seems to be fine.
I have a question about auth0 and next js.
For example, I have the next code (this code works)
//initialprops enables server-side rendering in a page and allows you to do initial data population
ModelsList.getInitialProps = async (ctx) => {
//this is static token to test from auth0.com
const accessToken = 'eyJhbG.....'
//fetching data
const res = await fetch('http://localhost:7071/api/bo/getModels', {
headers: {
Authorization: `Bearer ${accessToken}`
}
})
const json = await res.json()
return { data: json }
}
As you can see, I have accessToken variable as a text. It's a problem for me
How can make accessToken dynamic?
Thanks a lot!
P.S please, dont reference to auth0 documentation, I have tried a lot. Provide, please, a real solution/example.
Ok, so this is what worked for me.
Let's say you've got api.example.com/resources. This where data actually is. You will need to proxy via next's api.
Inside your jsx component, you fetch next's api.
// components/Dashboard.jsx
const API_URL = "api/resources";
async function fetcher(url: any) {
const res = await fetch(url);
const json = await res.json();
return json;
}
function Dashboard() {
const { data, error } = useSWR(API_URL, fetcher);
if (error) return <div>failed to load</div>;
if (!data) return <div>loading...</div>;
return <div>show your resources here</div>;
}
and now inside the next's api file you can fetch the actual endpoint you need.
// api/resources.js
import {
getAccessToken,
getSession,
withApiAuthRequired,
} from "#auth0/nextjs-auth0";
export default withApiAuthRequired(async function healthcheck(req, res) {
const session = await getSession(req, res);
const token = session?.idToken;
const response = await fetch("https://api.example.com/resources", {
method: "GET",
headers: {
Authorization: `Bearer ${token}`,
},
});
const data = await response.json();
res.status(200).json(data);
});
if you get errors, check the jwts you're getting. Audience or scope mismatch errors are usually the main culprits.

Every time I run await Notifications.getExpoPushTokenAsync(); the same token is generated. The token looks like: ExponentPushToken[NgTr99YO5fy0EQM4R]. I am able to get push notifications to this token so I know it is formatted correctly, I am just confused as to why it keeps pushing the same token to me when it should generate a new one. What am I missing?
const registerForPushNotificationsAsync = async () => {
if (Constants.isDevice) {
const {status: existingStatus} = await Permissions.getAsync(
Permissions.NOTIFICATIONS
);
let finalStatus = existingStatus;
if (existingStatus !== "granted") {
const {status} = await Permissions.askAsync(Permissions.NOTIFICATIONS);
finalStatus = status;
}
if (finalStatus !== "granted") {
return;
}
token = await Notifications.getExpoPushTokenAsync();
} else {
alert("Must use physical device for Push Notifications");
}
if (Platform.OS === "android") {
Notifications.createChannelAndroidAsync("default", {
name: "default",
sound: true,
priority: "max",
vibrate: [0, 250, 250, 250],
});
}
return token;
};
followed this documentation:
https://docs.expo.io/guides/push-notifications/
My mistake. The duplicate tokens were being created based off of what device i was using to create a new token. In my case I was making multiple profiles on the same device so I was receiving the same token for each profile which was throwing me off.
All is working as it should be.
I have been working on a oauth2 flow for spotify by following this similar tutorial by the Firebase team for Instagram HERE
I am able to submit my credentials and return the user code and state in the url, but when I run the method to submit the code to return an auth token, the auth token that I print to console in the Firebase functions returns: Auth Token Error Not Found. Here's my workflow:
Here's the Spotify docs
FIRST, I have a function to configure my spotifyOAuth:
function spotifyOAuth2Client() {
// Spotify OAuth 2 setup
const credentials = {
client: {
id: functions.config().spotify.clientid,
secret: functions.config().spotify.clientsecret,
},
auth: {
tokenHost: 'https://accounts.spotify.com',
authorizePath: '/authorize'
},
};
return require('simple-oauth2').create(credentials);
}
I use that function in this Firebase function that is called using https://us-central1-<my project string>.cloudfunctions.net/redirect:
exports.redirect = functions.https.onRequest((req, res) => {
const oauth2 = spotifyOAuth2Client();
cookieParser()(req, res, () => {
const state = req.cookies.state || crypto.randomBytes(20).toString('hex');
console.log('Setting verification state:', state);
res.cookie('state', state.toString(), {
maxAge: 3600000,
secure: true,
httpOnly: true,
});
const redirectUri = oauth2.authorizationCode.authorizeURL({
redirect_uri: OAUTH_REDIRECT_URI,
//scope: OAUTH_SCOPES,
state: state,
});
console.log('Redirecting to:', redirectUri);
res.redirect(redirectUri);
});
});
The code above returns a url string with the proper parameters, the following code block is where my code breaks, I have another cloud function that runs after being redirected from the res.redirect(redirectUri) above. And when I try to run the getToken() method, it appears to not return anything because I hit the catch block instead? This is where I observe the Auth Token Error Not Found.
const oauth2 = spotifyOAuth2Client();
try {
return cookieParser()(req, res, async () => {
console.log('Received verification state:', req.cookies.state);
console.log('Received state:', req.query.state);
if (!req.cookies.state) {
throw new Error('State cookie not set or expired. Maybe you took too long to authorize. Please try again.');
} else if (req.cookies.state !== req.query.state) {
throw new Error('State validation failed');
}
console.log('Received auth code:', req.query.code);
console.log(OAUTH_REDIRECT_URI);
// Get the access token object (the authorization code is given from the previous step).
const tokenConfig = {
code: req.query.code,
redirect_uri: 'http://localhost:8100/popup'
};
// Save the access token
try {
const result = await oauth2.authorizationCode.getToken(tokenConfig)
const accessToken = oauth2.accessToken.create(result);
console.log('inside try');
console.log(result);
console.log(accessToken);
} catch (error) {
console.log('Access Token Error', error.message);
}
I've double checked my spotify client/secret credentials in the config, what is going wrong with this OAuth2 flow?
Resolved my issue, I was not using the correct endpoints:
const credentials = {
client: {
id: functions.config().spotify.clientid,
secret: functions.config().spotify.clientsecret,
},
auth: {
tokenHost: 'https://accounts.spotify.com',
authorizePath: '/authorize',
tokenPath: '/api/token'
},
};
I'm trying to make an app in Node to access my google calendar, so I followed the steps at https://developers.google.com/calendar/quickstart/nodejs but I'm getting Error: Error: No access, refresh token or API key is set..
Yes I have created the credentials.
Yes I have downloaded the json, renamed to client_secret.json and added to the application folder.
Here is the code:
const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');
const OAuth2Client = google.auth.OAuth2;
const SCOPES = ['https://www.googleapis.com/auth/calendar.readonly'];
const TOKEN_PATH = './client_secret.json';
try {
const content = fs.readFileSync('client_secret.json');
authorize(JSON.parse(content), listEvents);
} catch (err) {
return console.log('Error loading client secret file:', err);
}
function authorize(credentials, callback) {
const {client_secret, client_id, redirect_uris} = credentials.installed;
let token = {};
const oAuth2Client = new OAuth2Client(client_id, client_secret, redirect_uris[0]);
// Check if we have previously stored a token.
try {
token = fs.readFileSync(TOKEN_PATH);
} catch (err) {
return getAccessToken(oAuth2Client, callback);
}
oAuth2Client.setCredentials(JSON.parse(token));
callback(oAuth2Client);
}
function getAccessToken(oAuth2Client, callback) {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES,
});
console.log('Authorize this app by visiting this url:', authUrl);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.question('Enter the code from that page here: ', (code) => {
rl.close();
oAuth2Client.getToken(code, (err, token) => {
if (err) return callback(err);
oAuth2Client.setCredentials(token);
// Store the token to disk for later program executions
try {
fs.writeFileSync(TOKEN_PATH, JSON.stringify(token));
console.log('Token stored to', TOKEN_PATH);
} catch (err) {
console.error(err);
}
callback(oAuth2Client);
});
});
}
function listEvents(auth) {
const calendar = google.calendar({version: 'v3', auth});
calendar.events.list({
calendarId: 'primary',
timeMin: (new Date()).toISOString(),
maxResults: 10,
singleEvents: true,
orderBy: 'startTime', }, (err, {data}) => {
if (err) return console.log('The API returned an error: ' + err);
const events = data.items;
if (events.length) {
console.log('Upcoming 10 events:');
events.map((event, i) => {
const start = event.start.dateTime || event.start.date;
console.log(`${start} - ${event.summary}`);
});
} else {
console.log('No upcoming events found.');
}
});
}
Any ideas?
Can you confirm as following points again?
The files of const TOKEN_PATH = './client_secret.json'; and const content = fs.readFileSync('client_secret.json'); are the same.
Please modify from const TOKEN_PATH = './client_secret.json'; to const TOKEN_PATH = './credentials.json';, and run again.
By this, client_secret.json that you downloaded has already might be overwritten. So please also confirm this.
When an error occurs even if above modification was done, please confirm the version of googleapis. Because it has been reported that googleapis with v25.0.0 - v30.0.0. has some bugs for some APIs.
If you think a bug for the error, please modify the version of googleapis to v24.0.0. The error may be removed.
