Atlas Function with firebase-admin dependency failing to send push notification

ita · 2023-11-23T22:22:41.470Z

Hi there,

I have a SwiftUI app with Realm. I set up Firebase Messaging on the client code.

I’m trying to send a push notification to an iOS client from an Atlas Function.

I added ‘firebase-admin’ dependency.

Here’s the function:

async function sendPushNotification(token, title, body) {
  const admin = require('firebase-admin');
  
  const credentials = {
    projectId: '<project id>',
    clientEmail: '<client email>',
    privateKey: '<private key>',
  };

  admin.initializeApp({
   credential: admin.credential.cert(credentials)
 });
 
 const message = {
    notification:{
      body: body,
      title: title
    },
    token: token
  };

  try {
    await admin.messaging().send(message);
    console.log('Notification sent successfully');
  } catch (error) {
    console.error('Error sending notification:', error);
  }
}

I get the error: Error sending notification: FunctionError: TypeError: Value is not an object: undefined

Any ideas why this is happening?

I printed admin, admin.messaging(), and admin.messaging.send - they’re all fine (not undefined).
I also printed message, message.notification, message.token - also fine (not undefined).
And I tried to change the message’s notification object name to “data” - didn’t help.

Provide full error log which shows line numbers etc.

The only log printed (via Atlas Logs) is

Error:
Error sending notification: FunctionError: TypeError: Value is not an object: undefined

I’m using Atlas Function Editor, and I can tell based on debugging that the line where it fails is
await admin.messaging().send(message);

npm install firebase-admin@^10.0.0

### [REQUIRED] Step 2: Describe your environment * Operating System version…: MongoDB Atlas Trigger (Realm App) * Firebase SDK version: 11.4.1 * Firebase Product: messaging * JS SDK Version: [3.18.0](https://github.com/mongodb/stitch-js-sdk/releases/tag/v3.18.0) * NPM version: I don't know ### [REQUIRED] Step 3: Describe the problem Executing `admin.messaging().sendMulticast(message)` returns an error and is not working anymore after upgrading to `firebase-admin: 11.4.1` from `11.0.1` and with the release of [fastify/busboy 1.2.0](https://github.com/firebase/firebase-admin-node/issues/1902#issuecomment-1373978366) : ``` uncaught promise rejection: TypeError: Value is not an object: undefined ``` The difference with my previous issue #1902 is that now `messaging().sendMulticat(message)` is crashing and no longer deliver the push notification. #### Steps to reproduce: 1. Create a MongoDB Atlas trigger 2. Add `firebase-admin` as external dependency and make sure it's `11.4.1` 3. Add the service-account.json as a `value` 4. Run the code with the below code #### Relevant Code: ``` exports = async function() { const admin = require("firebase-admin"); const json_creds = context.values.get("service_account_value_name"); const title = "Test"; const body = "This is a test"; const message= { android: { notification: { title: title, sound: "default", body: body, }, }, apns: { payload: { aps: { alert: { title: title, body: body, }, mutableContent: 1, contentAvailable: 1 } }, }, tokens: ["device_token_1", "device_token_2"] }; admin.initializeApp({ credential: admin.credential.cert(JSON.parse(json_creds)) }); admin.messaging().sendMulticast(message); console.log("Messages sent !"); } } ```

Hey All, we had the same issue for sendMultiCast. Apparently Firebase deprecated in mid september the legacy support and is forcing the usage of new api which doesn’t support /batch that was used.

Installing the latest versions (12.4) does not work on the realm environment due to lack of full support for promises and the new jsonwebtokens npm package.

I created a customer version that works for the sendMultiCast (which can support sending ofc to a single token by providing an array with a single target token)
