🐛 [firebase_messaging] iOS failing to notify app

MATTYGILO commented 5 months ago

Bug report

Describe the bug I am trying to send notifications to my flutter app, but none are being received whether, background, foreground or terminated. All help is much appreciated

Note: I changed much of the code in the past because I need phone auth to work without captcha.

Steps to reproduce

AppDelegate.swift

import UIKit
import Flutter
import Firebase
import FirebaseMessaging

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }

  func application(application: UIApplication,
                   didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
      Messaging.messaging().apnsToken = deviceToken
  }
}

Capabilities:

Note: Cloud messaging legacy is disabled

I have tried both notifications to all and specific devices:

Expected behavior

To receive notifications in at least one of foreground, background or terminated

Sample project

main.dart:

import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_messaging/firebase_messaging.dart';
import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();

  // Run the app
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();

    // On build
    WidgetsBinding.instance.addPostFrameCallback((_) async {
      FirebaseMessaging messaging = FirebaseMessaging.instance;

      Map<Permission, PermissionStatus> statuses = await [
        Permission.notification
      ].request();

      NotificationSettings settings = await messaging.requestPermission(
        alert: true,
        badge: true,
        provisional: false,
        sound: true,
      );

      if (settings.authorizationStatus == AuthorizationStatus.authorized) {
        print("User granted permission");

        // Output the FCM token
        String? token = await messaging.getToken();

        // await messaging.getAPNSToken();

        print("app_main token: $token");
      } else if (settings.authorizationStatus == AuthorizationStatus.provisional) {
        print("User granted provisional permission");
      } else {
        print("User declined or has not accepted permission");
      }

      FirebaseMessaging.onMessage.listen((RemoteMessage message) {
        print('Got a message whilst in the foreground!');
        print('Message data: ${message.data}');

        if (message.notification != null) {
          print('Message also contained a notification: ${message.notification}');
        }
      });
    });

  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Firebase Messaging Test'),
        ),
        body: Center(
          child: Text('Listening for messages...'),
        ),
      ),
    );
  }
}

Additional context

I have tried a lot and haven't logged all that I have tried. All help would be much appreciated.

So I have started trying to send a notification from a firebase function:

exports.sendNotification = functions.region("europe-west2").https.onRequest(async (req:any, res: any) => {

    const token = req.query.token; // The FCM token of the device you want to send the notification to
    const message = req.query.message; // The message you want to send

    if (!token || !message) {
        return res.status(400).send("Missing token or message parameter.");
    }

    const payload = {
        notification: {
            title: "New Notification",
            body: message,
            icon: "default",
            click_action: "FLUTTER_NOTIFICATION_CLICK", // Custom click action for Flutter apps
        },
    };

    try {
        const response = await admin.messaging().sendToDevice(token, payload);
        console.log("Notification sent successfully:", response);
        res.send("Notification sent successfully");
    } catch (error) {
        console.log("Error sending notification:", error);
        res.status(500).send("Error sending notification: " + error);
    }
});

Which resulted in this error:

Failed to send notification. Status code: 500, Message: Error sending notification: Error: An error occurred when trying to authenticate to the FCM servers. Make sure the credential used to authenticate this SDK has the proper permissions. See https://firebase.google.com/docs/admin/setup for setup instructions. Raw server response: "<HTML>

I have verified that my Bundle ID, Team ID and App Store ID all match

MATTYGILO commented 5 months ago

I have revoked my APNs key and re uploaded it many times I have download my service-account.json and replaced it Xcode many times

MATTYGILO commented 5 months ago

As you can see my service account has all firebase admin cloud messaging permissions

I also tried this code using the new API but it didn't work either:

const payload = {
            message: {
                token: token, // Set the device token
                notification: {
                    title: "Notification Title", // Set a title for the notification
                    body: message, // Use the message passed in the query for the body
                },
                apns: {
                    headers: {
                        "apns-priority": "10",
                    },
                    payload: {
                        aps: {
                            alert: {
                                title: "Notification Title",
                                body: message,
                            },
                        },
                    },
                },
                webpush: {
                    headers: {
                        Urgency: "high",
                    },
                    notification: {
                        body: message,
                        requireInteraction: "true",
                    },
                },
            },
        };

        const response = await admin.messaging().send(payload.message);

It returned this error:

MATTYGILO commented 5 months ago

I tried the old API and it gave me this error:

A message targeted to an iOS device could not be sent because the required APNs SSL certificate was not uploaded or has expired. Check the validity of your development and production certificates.

However as I have revoked and re uploaded the Auth key to the server and I still get this error.

MATTYGILO commented 5 months ago

The dumbest mistake to make (Don't use TeamID from Xcode):

Go to App Store Connect, scroll to Membership details and use the value there (Use TeamID from AppStore connect)
