flutterfire 🐛 [firebase_messaging] APNS token has not been set yet. Please ensure the APNS token is available by calling getAPNSToken()

Bug report

I am trying to implement Push Notifications in my Flutter app. But I get the following error:

APNS token has not been set yet. Please ensure the APNS token is available by calling getAPNSToken().

Some of the steps I have done using the flutterfire_cli. But since I am using flavors, I also had to do some steps on my own, like having the configurations (different GoogleService-Info.plist for each flavor corresponding to the a different Firebase project) for different flavors inside a ios/config directory and using a script to copy these resources during build time.

Steps to reproduce

Steps to reproduce the behavior:

Create a Flutter project using flutter version 3.13.2
Integrate firebase_messaging: ^14.7.10 and firebase_core: ^2.24.2
Implement flavors for different environments, including the script used to copy the required resources to the correct directory (I can provide this later on, if needed as well)
Use the flutterfire_cli to generate initialization data for each flavor
Connect to an iOS device (I am using a real device, iPhone X with iOS 16.1.1)

Expected behavior

I would want Push notifications feature to work correctly in my iOS device

Additional context

The getAPNSToken() function always returns null in my case. I have checked multiple times the configurations within XCode for the bundle IDs to be correct and corresponding to their respective Firebase projects as well. The app runs exactly as intended in Android, and this issue is only for iOS devices.

I am using APNS Key instead of the APNS certificates for the projects. I mention this explicitly here because the docs have a title for the key but the content for the certificate (See: https://firebase.google.com/docs/cloud-messaging/flutter/client#upload_your_apns_authentication_key )

In Info.plist, I get the error, no matter if I set the FirebaseAppDelegateProxyEnabled to true or false. Along with that, I also get the error whether or not I do the following in my AppDelegate.swift

import Firebase

Firebase.configure()

Some answers in S/O & Github mention importing Firebase along with the code for configurations, and some only import the Firebase module. I have noticed that the code for configuration results in the app building and crashing immediately on startup, so I am a bit lost here as well.

I cannot solely rely on the CLI to do the work for me, as schemes/flavors are not yet fully supported by the CLI. (See issue: https://github.com/invertase/flutterfire_cli/issues/14 )

Possible resolve:

Also, related to https://github.com/firebase/flutterfire/issues/12070. The author of that issue has resolved it by downgrading their dependencies to a lower version, but I am not sure if that is the best way forward. If nothing else works, I will be using this as a last option, though.

Thanks for the report @praveengitsit-pro Check this and see if it helps to resolve your case or not.

@darshankawar The said solution does not work for me. I have added a delay of 5 seconds initially before calling getAPNSToken(). In fact, I cannot get the APNS token even if I call the method again some time later.

I am a little confused about having to call this method before doing anything else with FCM. Does this mean that if it runs into this error once, any subsequent calls to this method will not work? Or does this mean that you can delay the method call and it will work eventually?

I also think having to add a delay is not a sustainable solution. This should ultimately be fixed in the package we are using. And in the meantime, an acceptable delay time (like: 2s, 5s, etc) has to clarified in some documentation, too

I am able to Receive APNS tokes, but not message from FCM Console. From CloudKit just works with APNS, but from FCM with token, not.

using 10.20.0 pods

I upgraded my Flutter project to v3.16.9, and the error is still there. Since, the upgrade did not work, I think there might be something wrong with something else entirely

iOS directory structure

Inside each directory is a file named GoogleService-Info.plist for the respective Firebase projects of each of the flavors.

Custom script for copying `GoogleService-Info.plist`

PS. I am using zsh

setopt KSH_ARRAYS BASH_REMATCH
environment="default"

# Regex to extract the scheme name from the Build Configuration
# We have named our Build Configurations as Debug-dev, Debug-prod etc.
# Here, dev and prod are the scheme names. This kind of naming is required by Flutter for flavors to work.
# We are using the $CONFIGURATION variable available in the XCode build environment to extract 
# the environment (or flavor)
# For eg.
# If CONFIGURATION="Debug-prod", then environment will get set to "prod".
if [[ $CONFIGURATION =~ -([^-]*)$ ]]; then
environment=${BASH_REMATCH[1]}
fi

echo $environment

# Name and path of the resource we're copying
GOOGLESERVICE_INFO_PLIST=GoogleService-Info.plist

if [ ! -f $GOOGLESERVICE_INFO_FILE ]
then
echo "No GoogleService-Info.plist found. Please ensure it's in the proper directory."
exit 1
fi

# Get a reference to the destination location for the GoogleService-Info.plist
# This is the default location where Firebase init code expects to find GoogleServices-Info.plist file
PLIST_DESTINATION=${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app
echo "Will copy ${GOOGLESERVICE_INFO_PLIST} to final destination: ${PLIST_DESTINATION}"

# Copy over the prod GoogleService-Info.plist for Release builds

Update: Downgrading firebase dependencies still resulting in the same error

I even tried to use the solution proposed in this comment under a similar issue, and that option does not work either.

The said solution did land me in some other zone, where I found something I had previously missed to add in my Info.plist from the currently archived guide. Here, the issue was found to be:

flutter [FirebaseAnalytics][I-ACS023129] Network fetch failed. Will retry later. Code, error: 0, Error Domain=NSURLErrorDomain Code=-1004 "Could not connect to the server."

I added the necessary config but it resulted in the same of fetching APNS token as well as the network fail issue mentioned above. I also tried with the above key added to the plist with my previous configuration and there has been no progress there either.

Thanks for the details @praveengitsit-pro I am wondering if this occuring due to flavors you are using in the app. Is there a way for you to check if without flavors, do you still get same behavior or not ?

I have the same problem.

A few month ago I had the same issue, I had to downgrade to

  firebase_core: 2.7.1
  firebase_messaging: 14.2.6
  firebase_core_platform_interface: 4.5.3

And then with

  firebase_core: ^2.15.1
  firebase_messaging: ^14.6.7

It was fixed.

And the problem is back. I'm not sure which version is the problem now.

EDIT:

I tried to downgrade back to

  firebase_core: 2.15.1
  firebase_messaging: 14.6.7
  firebase_core_platform_interface: 4.8.0

I found these versions - with which I didn't get the error message - in pubspec.lock. And strangely enough, the error is present.

So I tried to downgrade even more, to the versions I had locked until the bug was fixed...

  firebase_core: 2.7.1
  firebase_messaging: 14.2.6
  firebase_core_platform_interface: 4.5.3

And it fixes the problem.

Here are some issues from when the bug appeared, if that helps... https://github.com/firebase/flutterfire/issues/10656 https://github.com/firebase/firebase-ios-sdk/issues/11459

Yes, I can still reproduce the issue by creating a separate Flutter project and setting up Firebase entirely from the flutterfire_cli.

Update: Not working with a similar issue on another project

Tried with another project where notifications was previously working on the same physical device. And now, it is no longer working. So far as I can recall, the only thing that is different during when the notifications was previously working and now is that I have upgraded my development machine's version (to Mac 14.3) along with XCode and Command line tools. It is likely that the phone's OS was also upgraded but this I can't say with certainty.

Thanks for the details and your patience while we figure this out @praveengitsit-pro Can you verify if this only occurs on device or while running on simulator too ? That'll narrow down the issue occurs on both or is specific to either simulator or physical device.

@praveengitsit-pro can you confirm if firebase is connected with apple.

"So in order to get Firebase push notifications to work, you need to create an APNs authentication key and add it to Firebase. Luckily this is simple to do. Log into your Apple Developer account, then under Certificates, Identifiers & Profiles click on Keys. Click the + button to register a new key."

@darshankawar I thought the Push Notifications feature were something to be tested on a physical device so hadn't given it much thought lately. To my utter surprise, the codebase works in iPhone 14 - iOS 16.4 simulator, meaning I receive both the APNS token as well as the FCM token. I did do one following change to my Podfile though.

# Uncomment this line to define a global platform for your project
platform :ios, '12.0'

@flakerimi Not sure what you mean by confirming the connection but I have double-checked my APNS key and Firebase setup. It is also mentioned in the original issue.

That is correct. This is from xcode 14 release notes.

Reiterating this as it was also backed by the team to be the solution.

Adding a one-second delay just before calling "getAPNSToken" seems to correct the problem. Below that, no (tested with 500 milliseconds). But... 1 second is a lot and doesn't seem right...

On top of that, it worked fine without this delay a few weeks/months ago, and I haven't changed anything on this piece of code since...

Hey @praveengitsit-pro. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

I am able to make the notifications work for iOS in a build for Test Flight, as well as in debug mode by directly connecting to my dev machine. The delay, as mentioned before, makes it work. (Tested on iPhone 15 Pro physical device)

Still facing issues building it for iPhone X in debug mode but I think I'll be moving on from this right now.

Feb 23 '24 13:02 praveengitsit-pro

Should we really close this ticket? Adding a one-second delay doesn't seem like a fix to me, but more like a workaround until the bug is properly addressed...

Feb 23 '24 13:02 smbpunt

@Punt13140 I agree with you that this is more a hack at the moment. I don't know if the team will be working on this anytime soon, but will keep it open until a proper resolve is addressed.

Feb 23 '24 14:02 praveengitsit-pro

this as also mentioned above earlier is a likely solution, but will keep the issue open and label for team's input / attention if this need another re-look.

There is nothing we can do from our end, the APNS token is delivered to this delegate method, sometimes it arrives quickly, sometimes not. You have to design your app in a way that ensures it has arrived before making firebase messaging API calls. A Completer is useful in this scenario: https://api.flutter.dev/flutter/dart-async/Completer-class.html

Is this really a recommended approach? Design our apps to wait somehow (how long and when?) and hope that token will be available.

We are initializing Firebase Messaging on application startup and cant block user's flow by some magic constant delay to make notifications work.

I don't have knowledge about native's ios part, but is there really no way to system tell us that token is available though callback or similar?

Any update?

I got same erorr, but it fixed after upgrate my iphone to last iOS. Error still here, but push notifications are work

You can update the "AppDelegate.swift" like that

import UIKit
import Flutter
import FirebaseCore
import FirebaseMessaging

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }

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