Error on Heroku when trying to post data ( error:0909006C Pem routines..._

I am trying to make a small nodeJS server deployed on Heroku, saving data to Firestore database. The server is deployed and running correctly.
I use Insomnia to test my requests and when I use it locally I can send a post request and save my data object to the database without issues. However, when I try to send a post request to Heroku, I get a 500 error with this message:
{ "code": 16, "details": "Failed to retrieve auth metadata with
error: error:0909006C:PEM routines:get_name:no start line",
"metadata": {}, "note": "Exception occurred in retry method that was
not classified as transient" }
I have read that it is necessary to add real line breaks in the env variable but I guess I am doing it already. This is my initializeApp function:
admin.initializeApp({
credential: admin.credential.cert({
projectId: process.env.PROJECT_ID,
privateKey: process.env.PRIVATE_KEY
? process.env.PRIVATE_KEY.replace(/\\n/gm, "\n")
: undefined,
clientEmail: process.env.CLIENT_EMAIL
}),
databaseURL: "XXXXX"
});
Any idea how to fix this?

I solved it by copy-pasting the key with break lines directly into Heroku config variables and removing .replace(/\\n/gm, "\n") from the code.
privateKey: process.env.PRIVATE_KEY
? process.env.PRIVATE_KEY
: undefined

Firebase Storage in Web Application: storage.useEmulator is not a function

In my local web application development environment the web application is accessing the Firestore emulator correctly, but not the Storage emulator. Instead it accesses the production storage.
I load the module from http://localhost:5000/__/firebase/8.3.0/firebase-storage.js
I have tried this from https://firebase.google.com/docs/emulator-suite/connect_storage#web-v8:
var storage = firebase.storage();
storage.useEmulator("localhost", 9199);
But the useEmulator function does not exist. How can this be?

The function storage.useEmulator was introduced in a later version of firebase.

Have you configured your connection before opening it?
var firebaseConfig = {
apiKey: '<your-api-key>',
authDomain: '<your-auth-domain>',
databaseURL: '<your-database-url>',
storageBucket: '<your-storage-bucket-url>'
};
firebase.initializeApp(firebaseConfig);
And, I don't have direct xperience about it, but have you tried this way?
firebase.storage.useEmulator('localhost', xxxx)
And beware this could be a work in progress stuff: try this cmd:
firebase --open-sesame storageemulator

firebase-messaging.js not found laravel

Hello everyone I am making an application using firebase for push notifications. This is my first project in firebase. The issue I am having is with the connection as when I run the project and click on the login button it gives me
Notification permission granted
But after this it returns an error which is as follow.
A bad HTTP response code (404) was received when fetching the script.
firebase.js:24 Unable to get permission to notify. FirebaseError: Messaging: We are unable to register the default service worker. Failed to register a ServiceWorker for scope ('http://localhost:8000/firebase-cloud-messaging-push-scope') with script ('http://localhost:8000/firebase-messaging-sw.js'): A bad HTTP response code (404) was received when fetching the script. (messaging/failed-serviceworker-registration).
at https://www.gstatic.com/firebasejs/7.5.2/firebase-messaging.js:1:44674
I don't know why it is happening as I can see my js file and all the code as well, here is my config files.
In my firebase-messaging-sw.js which is on root directory the code is
importScripts('https://www.gstatic.com/firebasejs/7.5.2/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/7.5.2/firebase-messaging.js');
firebase.initializeApp({
'messagingSenderId': 'SenderID'
});
const messaging = firebase.messaging();
console.log(messaging);
messaging.setBackgroundMessageHandler(function(payload) {
console.log('[firebase-messaging-sw.js] Received background message ', payload);
// Customize notification here
const notificationTitle = 'Background Message Title';
const notificationOptions = {
body: 'Background Message body.',
icon: '/firebase-logo.png'
};
return self.registration.showNotification(notificationTitle,
notificationOptions);
});
And in my firebase.js file the code is as follow:
const firebaseConfig = {
apiKey: "API-KEY",
authDomain: "authDomain",
databaseURL: "DBURI",
projectId: "P-ID",
storageBucket: "SB",
messagingSenderId: "SenderID",
appId: "AppID",
measurementId: "MeasurementID"
};
firebase.initializeApp(firebaseConfig);
//------------------------------------------------------------------------------
const messaging = firebase.messaging();
messaging.requestPermission().then(function () {
console.log("Notification permission granted");
return messaging.getToken();
}).then(function (token) {
console.log(token);
}).catch(function (err) {
console.log("Unable to get permission to notify.", err);
});
//------------------------------------------------------------------------------
messaging.onMessage((payload) => {
console.log(payload);
})
Any help would be appreciated. Thank you in advance.

I found the solution and it's working perfectly fine. Posting it for others who faces similar problem. The issue was in my firebase-messaging-sw.js file. I was initializing the firebase with sender id it was written in the documentation. I just initialized the firebase object with all the configuration values changing the initializing object solved my problem.

Firebase Admin With Credential

After coding some of my firebase functions, I deployed and got the following error:
Unexpected error while acquiring application default credentials: Could not load the default credentials.
I researched this error and came to the conclusion that this post would solve my issue: Firebase Cloud Functions: Error: Unexpected error while acquiring application default credentials: read ECONNRESET
I tried this solution. I downloaded a new private key to my desktop and then inserted the following code:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
var serviceAccount = require('/Users/nikhilsridhar/Desktop/test-eed0a-firebase-adminsdk-c4tmt-5d905a082b.json');
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://test-eed0a.firebaseio.com"
});
However this does not solve my problem, but rather gives me a new error:
Error: Cannot find module '/Users/nikhilsridhar/Desktop/test-eed0a-firebase-adminsdk-c4tmt-5d905a082b.json'
What am I doing wrong?

So after some time I figured out that the service account file must be within the functions folder. Then make the path relative or in my example: ./test-eed0a-firebase-adminsdk-c4tmt-5d905a082b.json. This should work.

The function admin.credential.cert() receives a string parameter with the path of the firebase json key, this code works well for me with the auth method, you should add databaseURL and call .firestore() instead of auth():
import admin from 'firebase-admin'
export default admin.initializeApp({
credential: admin.credential.cert('../../firebase-key.json')
}).auth()
Watch what TypeScript says about that method:
cert(serviceAccountPathOrObject: string | admin.ServiceAccount, httpAgent?: Agent | undefined): Credential
Optional | HTTP Agentto be used when retrieving access tokens from Google token servers.
The path to a service account key JSON file or an object representing a service account key.
See | Initialize the SDK for more details.
#example
// Providing a path to a service account key JSON file
const serviceAccount = require("path/to/serviceAccountKey.json");
initializeApp({
credential: cert(serviceAccount),
databaseURL: "https://<DATABASE_NAME>.firebaseio.com"
});
#example
// Providing a service account object inline
initializeApp({
credential: cert({
projectId: "<PROJECT_ID>",
clientEmail: "foo#<PROJECT_ID>.iam.gserviceaccount.com",
privateKey: "-----BEGIN PRIVATE KEY-----<KEY>-----END PRIVATE KEY-----\n"
}),
databaseURL: "https://<DATABASE_NAME>.firebaseio.com"
});
#returns
A credential authenticated via the provided service account that can be used to initialize an app.

upload file on firebase web using node js throws error firebase.storage is not a function

i created a web app using node js express and firebase. i created a form which will upload a file to firebase but when i tried what's on the guide it gives an error..
var firebase = require('firebase');
var config = {
apiKey: "----------------------------------",
authDomain: "----------------------------------",
databaseURL: "-",----------------------------------
projectId: "---------",
storageBucket: "----------------",
messagingSenderId: "---------------"
};
firebase.initializeApp(config);
module.exports = firebase;
// Get a reference to the storage service, which is used to create references in your storage bucket
var storage = firebase.storage();
// Create a storage reference from our storage service
var storageRef = storage.ref();
this is the set up i use for using firebase on node js.
var storage = firebase.storage();
^
TypeError: firebase.storage is not a function
and this is the error i receive from the console. after searching they said that i need to use google-cloud npm. so my question is if i install google-cloud on my node do i need to create an account on google cloud platform?..

Node js google-cloud package is used instead of firebase to store files, videos etc. Right now firebase storage is not compatible with Nodejs that's why you are getting that error^, yoou can do something like this to use google-cloud:-
npm install --save google-cloud
And then to use storage in your project this is a sample code:-
const gcloud = require('google-cloud');
const storage = gcloud.storage({
projectId: //project id here,
keyFilename: //service account credentials here,
});
const storagebucket = storage.bucket('projectID.appspot.com');
This link here has the complete guide how to do google-cloud stuff.
