I'm trying to get an emphemoral key from stripe using firebase functions. Here is the error I see in my firebase logs:
getStripeEphemeralKeysUnhandled error TypeError: Cannot read property 'create' of undefined at exports.getStripeEphemeralKeys.functions.https.onCall (/workspace/index.js:40:42) at func (/workspace/node_modules/firebase-functions/lib/providers/https.js:273:32) at process._tickCallback (internal/process/next_tick.js:68:7)
Here is the error that shows in the xcode console:
Error creating ephenmeral key: Error Domain=com.firebase.functions Code=13 "INTERNAL" UserInfo={NSLocalizedDescription=INTERNAL} INTERNAL
firebase function written in Javascript:
const functions = require('firebase-functions');
const stripe_key = "sk_test_LT2Wc4v9kUD6XxG8Nq2LNh4P00thTqtiSa"
const admin = require('firebase-admin');
var stripe = require('stripe')(stripe_key);
admin.initializeApp(functions.config().firebase);
exports.createStripeCustomer = functions.https.onCall(async (data, context) => {
const full_name = data.full_name;
const email = data.email;
const customer = await stripe.customers.create({
email: email,
name: full_name,
description: full_name
});
console.log('new customer created: ', customer.id)
return {
customer_id: customer.id
}
});
exports.getStripeEphemeralKeys = functions.https.onCall(async (data, context) => {
const api_version = data.api_version;
const customer_id = data.customer_id;
const key = await stripe.ephemeralKeys.create (
{customer: customer_id},
{apiVersion: api_version}
);
return key;
});
iOS call using swift
func createCustomerKey(withAPIVersion apiVersion: String, completion: #escaping STPJSONResponseCompletionBlock) {
let stripe_customer_id = MyDefaults.getDefaultsForCustID()
functions.httpsCallable("getStripeEphemeralKeys").call(["api_version" : apiVersion, "customer_id" : stripe_customer_id]) { (response, error) in
if let error = error {
completion(nil, error)
}
if let response = (response?.data as? [String: Any]) {
completion(response, nil)
}
}
}
I'm not versed enough in Javascript to know what the error means except there seems to be a problem with the word create. Any thoughts are much appreciated!
OK Thanks #floatingLomas #Rafael Lemos. You guys were on the right track. It was the stripe version. I was having some pod errors that I was pushing to fix later so cleaned up and updated cocoa pods ruby and npm... now when I firebase deploy - I finally got the right version of stripe up to firebase...
I"M GOOD NOW -- THANKS!!!

I am trying to deploy a callable firebase cloud function to generate an email verification link and then send an email with sendgrid containing the link.
When I deploy I keep getting the error
"code":3,"message":"Function failed on loading user code. This is likely due to a bug in the user code. Error message: Error: please examine your function logs to see the error cause".
I have succesfully deployed 4 other functions so my firebase & other env variables do not seem to be the problem.
Here is my code:
const functions = require("firebase-functions");
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const sgMail = require('#sendgrid/mail');
const API_KEY = functions.config().sendgrid.key;
const TEMPLATE_ID = functions.config().sendgrid.template;
sgMail.setApiKey(API_KEY);
exports.sendEmailVerifications = functions.https.onCall((email,context) => {
admin.auth().generateEmailVerificationLink(context.auth.token.email).then((link) => {
const msg = {
to: context.auth.token.email,
from: 'example#example.com',
template: TEMPLATE_ID,
dynamic_template_data: {
emailLink: link
}
};
sgMail.send(msg);
return {"success": true};
}).catch((error) => {
});
});
I am trying to log each time an account is created and deleted.
I created a trigger functions.auth.user().onCreate() and as I understand it returns an user object as in the docs: here, and here.
The functions deploy without trouble but when the trigger is called it throws an error:
Error: Process exited with code 16

Error which I cannot understand.
Here is my code
// functions/index.js
const functions = require('firebase-functions')
const admin = require('firebase-admin')
const { google } = require('googleapis')
const { firestore } = require("firebase-admin");
exports.logging = require('./logging');
admin.initializeApp()
// And other working functions
The actual functions
// functions/logging.js
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const { firestore } = require('firebase-admin');
const authUserTrigger = functions.auth.user()
exports.userSignup = authUserTrigger.onCreate((user) => {
storeUser(user)
})
exports.userDelete = authUserTrigger.onDelete((user) => {
storeUser(user)
})
async function storeUser(user) {
// functions.logger.log(user.email) -> this works
// Destructured original object
let updatedUser = (({ displayName, email }) => ({ displayName, email }))(user);
functions.logger.log('updatedUser', updatedUser )
await admin
.firestore()
.collection('logs')
.doc('users')
.collection('signup')
.set({
user: {updatedUser}, // I think this is the culprint
// user, This doesn't work either
createTimestamp: firestore.FieldValue.serverTimestamp()
}, { merge: true })
};
Thank you in advance
EDIT ==========
#Tanay was right. Needed to change set to add.
As #Tanay stated, you cannot use set() in a collection in Firebase, it must be a document. If you want to add a document to the collection with an auto ID then you can use add() on the collection with the data.
I am trying to write a cloud function to export only the new documents getting added to my 'reviews' sub-collection. The trigger for this cloud function is: Cloud Firestore. However, my cloud function deployment fails through the console. Could someone please help me understand what's wrong with my cloud function?
Error message:
Deployment failure:
Build failed: /workspace/index.js:26

Cloud function code:
const firestore = require('#google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
const bucket = 'gs://bucket_name'
exports.scheduledFirestoreBackup = (event, context) => {
const databaseName = client.databasePath(

return client

collectionIds: ['reviews'],
})
.onSnapshot()
.then(snap => {
snap.forEach(doc => {
const response = doc.data();
console.log(doc.data());
return response;
}
});
Console snippet:
The message you are getting, SyntaxError: missing ) after argument list is pretty clear. You are missing the closing curly bracket} and parenthesis) of then(). It should look something like this:
const firestore = require('#google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
const bucket = 'gs://bucket_name'
exports.scheduledFirestoreBackup = (event, context) => {
const databaseName = client.databasePath(
// process.env.GCLOUD_PROJECT,
"fs124",
'(default)'
);
return client
.exportDocuments({
name: databaseName,
outputUriPrefix: bucket,
collectionIds: ['reviews'],
})
.onSnapshot()
.then(snap => {
snap.forEach(doc => {
const response = doc.data();
console.log(doc.data());
return response;
});
});
};
I have updated the question as found the root cause of the issue.
As I have hosted my React SSR app which uses firebase database in the client serving by one of the cloud function named app throwing an error of Error: FIREBASE FATAL ERROR: Database initialized multiple times. Please make sure the format of the database URL matches with each database() call.. When I comment out one by one and deploy, works perfectly. But when I deploy together doesn't work. How do I separate these two keeping both at the same repo?
ORIGINAL Question: Why firebase cloud function throwing an error of 'The default Firebase app does not exist.'?
So I am trying out firebase function for the first time. admin.messaging() throwing me the following error. Help me figure out why?
If I look at the console I get results till console.log('deviceToken', deviceToken);
so whats wrong in const messageDone = await admin.messaging().sendToDevice(deviceToken, payload);?
const functions = require('firebase-functions');
const admin = require('firebase-admin');
exports.updateUnreadCount = functions.database.ref('/chats/{chatId}/{messageId}')
.onCreate(async(snap, context) => {
const appOptions = JSON.parse(process.env.FIREBASE_CONFIG);
appOptions.databaseAuthVariableOverride = context.auth;
const adminApp = admin.initializeApp(appOptions, 'app');
const { message, senderId, receiverUid } = snap.val();
console.log(message, senderId, receiverUid);
console.log('------------------------');
const deleteApp = () => adminApp.delete().catch(() => null);
try {
const db = adminApp.database();
const reciverUserRef = await db.ref(`users/${receiverUid}/contacts/${senderId}/`);
console.log('reciverUserRef', reciverUserRef);
const deviceTokenSnapshot = await reciverUserRef.child('deviceToken').once('value');
const deviceToken = await deviceTokenSnapshot.val();
console.log('deviceToken', deviceToken);
const payload = {
notification: {
title: 'Test Notification Title',
body: message,
sound: 'default',
badge: '1'
}
};
const messageDone = await admin.messaging().sendToDevice(deviceToken, payload);
console.log('Successfully sent message: ', JSON.stringify(messageDone));
return deleteApp().then(() => res);
} catch (err) {
console.log('error', err);
return deleteApp().then(() => Promise.reject(err));
}
});
Update1: According to this https://firebase.google.com/docs/cloud-messaging/send-message#send_to_a_topic, admin.messaging().sendToDevice(deviceToken, payload) APIs are only available in the Admin Node.js SDK?
So switched to
const payload = {
data: {
title: 'Test Notification Title',
body: message,
sound: 'default',
badge: '1'
},
token: deviceToken
};
const messageDone = await admin.messaging().send(payload);
Which is not working either. Getting an error Error: The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services. Any lead will be helpful.
EDIT: Finally got the function working.
My index.js is exporting to functions, follwoing
exports.app = functions.https.onRequest(app); //React SSR
exports.updateChat = functions.database.ref('/chats/{chatId}/{messageId}').onCreate(updateChat);
exports.app is a react ssr function, which I am using to host my site. This uses database too. and throwing error of multiple database instance.
When I comment out one by one and deploy, works perfectly. But when I deploy together doesn't work. How do I separate these two keeping both at the same repo? Any suggestions, please?
You can initialise db outside export function.
const admin = require('firebase-admin');
const adminApp = admin.initializeApp(appOptions, 'app')
//continue code
Update:
const admin = require('firebase-admin');
const adminApp = admin.initializeApp(options);
async function initialize(options, apps = 'app') {
try {
const defaultApp = adminApp.name
if(defaultApp) {
const adminApp1 = admin.initializeApp(apps);
}else {
const adminApp1 = admin.initializeApp(options, apps);
}
}catch(err) {
console.error(err);
}
}
Modify this snippet as per your need and try it out
It abstracts initialize of app in another function. Just call this function at appropriate place in your code.
Sorry if this seems like a really basic question, the concept of cloud functions is extremely new to me and i'm still highly in the learning process.
However, whilst trying to execute this cloud function i get the following error
TypeError: Cannot read property 'data' of undefined
Full log can be seen here
For reference as well, I didnt make this function, im just trying to get it working, i used this video.
The actual cloud function:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const firestore = admin.firestore();
const settings = { timestampInSnapshots: true };
firestore.settings(settings);
const stripe = require('stripe')(functions.config().stripe.token);
exports.addStripeSource =
functions.firestore.document('cards/{userid}/tokens/{tokenid}')
.onCreate(async (tokenSnap, context) => {
var customer;
const data = tokenSnap.after.data();
if (data === null) {
return null
}
const token = data.tokenId;
const snapchat = await
firestore.collection('cards').doc(context.params.userId).get();
const customerId = snapshot.data().custId;
const customerEmail = snpashot.data().email;
if (customerId === 'new') {
customer = await stripe.customers.create({
email: customerEmail,
source: token
});
firestore.collection('cards').doc(context.params.userId).update({
custId: customer.id
});
}
else {
customer = await stripe.customers.retrieve(customerId)
}
const customerSource = customer.sources.data[0];
return firestore.collection('cards').doc(context.params.userId).collection('sources').doc(customerSource.card.fingerprint).set(customersource, { merge: true });})
The dart code im using for writing a payment service:
import 'package:firebase_auth/firebase_auth.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
class PaymentService {
addCard(token) {
FirebaseAuth.instance.currentUser().then((user) {
print("Found User");
Firestore.instance
.collection('cards')
.document(user.uid)
.collection('tokens')
.add({'tokenId': token}).then((val) {
print('saved');
});
});
}
}
And finally, what executes when i push the button:
StripeSource.addSource().then((String token) {
print("Stripe!");
PaymentService().addCard(token);
});
As you can see the code is clearly being triggered, but i guess there is some sort of error with the data var, JavaScript is brand new to me so im sure its some sort of very dumb syntax issue.
From the log image attached the error is context is not defined
functions.firestore.document('cards/{userid}/tokens/{tokenid}')
.onCreate(async (tokenSnap, conetxt) => {
In the above function, you have passed parameter as conetxt and later in the function context is used, because of which it is giving undefined error.
Change the parameter name conetxt to context.
As your provided log output explains : you need to define a reference for your firestore.document function :
functions.firestore.document('cards/{userid}/tokens/{tokenid}')
modify it to :
functions.firestore.documentReference(){
}
