[<Firebase_Auth>] Unhandled Platform Exception Before Able to Catch SignInWithEmailAndPassword FirebaseAuthException

[GrahamDi]

3341 Relates to this.

Bug Description

I have just upgraded to the new FlutterFire library and am experiencing the above with the new version of firebase_auth (0.18.0+1), which did not occur in the previous version I used (0.16.1).

Here is a code snippet of my email/password authentication method.

auth.User _user;
          try {
            _user = (await _firebaseAuth.signInWithEmailAndPassword(
              email: email,
              password: password,
            ))
                .user;                    
          } on auth.FirebaseAuthException catch (e) {
            printMessage("FirebaseAuthException code: ${e.code}",
                isErrorMessage: true);
            _determineErrorCode(e);
            _user = null;
          } on Exception catch (e) {
            printMessage("Exception code: ${e.toString()}",
                isErrorMessage: true);
            _determineErrorCode(e);
            _user = null;
          }

The problem is that a platform exception is being triggered immediately after the call to signInWithEmailAndPassword and before the on auth.FirebaseAuthException catch (e) { block. The exception stops the code (unless I uncheck breakpoints, unhandled exceptions in my VSCode debugger - I see from the issue referenced above that it worked in Android Studio but it is not clear if AS was set to trap unhandled errors. I don't know AS that well.)

The exception occurs at line 572 in C:\flutter\packages\flutter\lib\src\services\message_codecs.dart

if (errorCode is String && (errorMessage == null || errorMessage is String) && !buffer.hasRemaining)
line 572 =>      throw PlatformException(code: errorCode, message: errorMessage as String, details: errorDetails);
    else
      throw const FormatException('Invalid envelope');
  }

The error message thrown is:

Exception has occurred. PlatformException (PlatformException(firebase_auth, com.google.firebase.auth.FirebaseAuthInvalidUserException: There is no user record corresponding to this identifier. The user may have been deleted., {code: user-not-found, additionalData: {}, message: There is no user record corresponding to this identifier. The user may have been deleted.}))

This is called from line 361 in C:\flutter\packages\flutter\lib\src\services\platform_channel.dart

Future<Map<K, V>> invokeMapMethod<K, V>(String method, [ dynamic arguments ]) async {
line 361=>    final Map<dynamic, dynamic> result = await invokeMethod<Map<dynamic, dynamic>>(method, arguments);
    return result?.cast<K, V>();
  }

If I continue the code run then the FirebaseAuthException block processes the firebase exception correctly. Similarly, if I turn off the unhandled exceptions check, the platform error is not seen and the FirebaseAuthException block shows the correct error message.

Steps to Reproduce

Simply enter an non-existant or badly formatted email address, or an invalid password to an existing address as the parameters to the signInWithEmailAndPassword method and the platform error will occur.

Expected behavior

I would expect the platform error not to occur or to propagate the error correctly ie. to be handled.

Hi @GrahamDi, I tried below code sample on latest dev and was able to see expected FirebaseAuthException, if I put an invalid email or password for signInWithEmailAndPassword() method.

void _signIn() async {
    try {
      User user = (await FirebaseAuth.instance.signInWithEmailAndPassword(
          email: _emailController.text, password: _passController.text)).user;
    }
    on FirebaseAuthException catch (e) {
      if (e.code == 'user-not-found') {
        print('No user found for that email.');
      } else if (e.code == 'wrong-password') {
        print('Wrong password provided for that user.');
      }
    }
  }

I/flutter ( 7067): No user found for that email.
I/flutter ( 7067): No user found for that email.

flutter doctor -v

``` [✓] Flutter: is fully installed.

I followed this example. Can you try same and see if it works for you ? Thanks.

@darshankawar
Hi,

Did you run this in VSCode in debug mode and was the Uncaught Exceptions box in the Breakpoints section ticked? It appears from your flutter doctor that you used Android Studio only. So we are not comparing apples with apples. As I mentioned above and is highlighted in the referenced issue at the top...it appears to work in Android Studio, but VSCode picks up an unhandled exception when running in debug mode with unhandled exceptions ticked. This exception did not manifest itself in version 0.16.1

[darshankawar]

@GrahamDi, You are correct. I tried it on AS, since I don't have VSCode.

[GrahamDi]

@darshankawar

Ok, will someone else be able to check this issue using VSCode?

[darshankawar]

@GrahamDi, let me try on VSCode.

[darshankawar]

@GrahamDi,

On latest master in VSCode, unable to see the exception:

code sample

``` import 'package:firebase_auth/firebase_auth.dart'; import 'package:firebase_core/firebase_core.dart'; import 'package:flutter/material.dart'; import 'package:flutter_signin_button/flutter_signin_button.dart'; import './register_page.dart'; import './signin_page.dart';Future main() async { WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp(); runApp(MyApp()); }class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Material App', theme: ThemeData.dark(), home: Home(), ); } }class Home extends StatelessWidget { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Material App Bar'), ), body: Center( child: Container( child: Text('Hello World'), ), ), floatingActionButton: FloatingActionButton( child: Icon(Icons.add), onPressed: () async => _signIn(), ), ); } void _signIn() async { try { User user = (await FirebaseAuth.instance.signInWithEmailAndPassword( email: 'me@google.com', password: '123456')) .user; } on FirebaseAuthException catch (e) { if (e.code == 'user-not-found') { print('No user found for that email.'); } else if (e.code == 'wrong-password') { print('Wrong password provided for that user.'); } } } } ```

[GrahamDi]

@darshankawar

That's very strange. I'm still seeing it with Flutter Channel stable, 1.20.3 and Dart 2.9.2

I will try and do some more investigation when I get time. Guess you may as well close this.

[Salakar]

@GrahamDi what version of firebase_auth are you on, you skipped a section on the issue template:

@jhandaya @Salakar @darshankawar This is the same platform exception at the same place that I am seeing and that stops my code before on FirebaseAuthException traps anything.

[jaxnz]

Yes - getting the same Platform Exception after updating - I get this error when running flutter pub deps -- --style=compact

flutter pub deps -- --style=compact
Could not find a file named "pubspec.yaml" in "C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\cloud_firestore-0.14.0+2".
pub finished with exit code 66

[darshankawar]

I am able to replicate this issue on latest stable (1.20.3) while debugging signInWithEmailAndPassword() method from firebase_auth's official example in Android Studio on Android device 8.1.0.

Steps to replicate:

1. Run firebase_auth official example plugin.
2. Tap on Test SignIn/SignOut.
3. Put debugger on void _signInWithEmailAndPassword() method and run in debug mode.
4. Enter valid email and invalid password and hit submit.
5. Debug the method and observe that it throws PlatformException, as shown in screenshots above.

[jaxnz]

This is still a major issue - is there any update?

[andresluna17]

this the problem This problem continues to appear, in the previous version 0.16 there is no problem, in 0.18 it also presents me with this error, the solution in my case was to use version 0.16

[ocastx]

@darshankawar As there are no updates on this issue: Is this something that is worked on? Or waiting for more details?

This seems to be a rather major issue because the exception is not catchable and debug apps are crashing on simple errors (like 'wrong-password')

[jslattery26]

I'm still having this issue as well. Can't catch any errors around creating and signing in to accounts.

[GrahamDi]

@darshankawar Would be nice to have an idea of what the likely next steps are and some idea of when. I see no one is assigned to this yet.

This is, after all, a rather key package in the Flutter / Firebase environment.

[Ehesp]

So I guess this is an oversight of internally throwing an exception internally, and expecting the error to be caught (handled) in user-land code.

I'll pick this one up next week - it's somehow being classes as unhandled even after being wrapped in a try-catch.

I suspect this comment is the same/similar issue with async/awaits.

[GrahamDi]

Much appreciated. When you sort it out, please would you let us know how it should have been handled in 'userland' ie.why my try/catch, which does have async/await, did not pick it up. Thanks a lot.

[Ehesp]

This issue is also very relevant: https://github.com/flutter/flutter/issues/33427

TLDR: This is a wider issue than this repo, however there is something which seems to pop up and that's when try/catch is used alongside a Future .catchError. I wonder whether wrapping the method channel calls within a try/catch and throwing will "fix" the issue. I'll have a dig into it and see what I come up with.

[GrahamDi]

Thanks for the other link, I hadn't spotted it. Also, having read through it I am sure I have also experienced 'sporadic' uncaught errors on flutter cached network image, which I see is mentioned, and other things and that I thought I should have trapped. Looks like there is something more fundamental going wrong here. Hope you can find it.

[ananth-hegde]

Sorry if this does not go where its supposed to, I'm still new to GitHub. Reading through, I've understood that using firebase_auth 0.16.1 will not end up with this exception going uncaught. Unfortunately, I don't have a week, I'm just a college student and my deadline is 3 days. I just wanted to know if my issue will be fixed if I use the previous version, and if someone has a link to it's documentation, I would be eternally in your favour

[GrahamDi]

Hi,

From what I am seeing, this issue causes a problem when debugging the app in Android Studio or VSCode and when uncaught exception tracking is turned on. When I run a release version on my phone the app behaves normally and I trap eg. a bad password or an invalid email address. So, I assume for your deadline you will be using a release version? Hence, there should be no problem.

Hope that helps.

Krgrds, Graham

Hey,

Thanks a lot. I'll be using a release version, yes. So I'll just need to catch it as a PlatformException or will it be covered under my FirebaseAuthException? Just need to know where the snackbar needs to be displayed.

[GrahamDi]

So, at the moment I am throwing the kitchen sink at it because of the strange uncaught exception. My try catch has: on PlatformException, on FirebaseAuthException, and on Exception / simple catch. I just make sure whichever block triggers, it provides an error message /code back to my UI so that I can show an error dialogue.

I'll do the same, just put the snackbar in both places and let the flutter gods take the wheel. Thanks a lot for your inputs, I've been grappling with this for the last 2 days and just came to know its not an error on my part. You're a lifesaver.

[GrahamDi]

Glad I could help. Good luck with your deadline and results. Let me know how it goes....and enjoy Flutter!

[Ehesp]

Yeah the issue here is with your IDEs handling exceptions (thinking its uncaught), so will be fine in prod, it's just an annoyance to deal with whilst testing.

I just wanted to know if my issue will be fixed if I use the previous version, and if someone has a link to it's documentation, I would be eternally in your favour

No docs exist before the current version sorry!

[Ehesp]

Ok managed to replicate and "fix".

https://github.com/flutter/flutter/issues/33427 pretty much sums up the overall issue (news to me!). Basically the .catchError statements within a try/catch aren't seen as a parent exception handler to the IDE so although Dart actually catches the error and deals with it (the reason why using the code without debugging works), the IDE kicks up a fuss.

I just converted everything to try/catch, and explicitly throw an exception.

Need to sort for the other plugins but if anyone can test my PR via pubspec git hash please do!

[ocastx]

Thanks, @Ehesp!

I just upgraded to the latest version again and experiencing the bug as well. Now I wanted to test your PR, but I am unsure if I configured the pubspec right for the package:

  #firebase_auth: "0.18.0+1" # Upgrade as soon as this is fixed https://github.com/FirebaseExtended/flutterfire/issues/3475
  firebase_auth: 
    git:
      url: git@github.com:FirebaseExtended/flutterfire.git
      ref: fix-3475
      path: 'packages/firebase_auth/firebase_auth'

Is this correct?

[Ehesp]

I think ref should be 7303514b501809431773cccec7ea0c0ba114529f, not sure if you need path either.

[ocastx]

Okay – I set path because if I don't I get the following error

Could not find a file named "pubspec.yaml" in git@github.com:FirebaseExtended/flutterfire.git 7303514b501809431773cccec7ea0c0ba114529f.
pub get failed (1; Could not find a file named "pubspec.yaml" in git@github.com:FirebaseExtended/flutterfire.git 

Which I think is correct because the pubspec is in the sub-folder of the package (packages/firebase_auth/firebase_auth)

[ghost]

I still have this issue, did you get it solved?

[andresluna17]

This is not a problem with the firebaseAuth library but with your editor or IDE

[GrahamDi]

@andresluna17 Not true. Read https://github.com/FirebaseExtended/flutterfire/issues/3475#issuecomment-701233145

[intraector]

any news on this?
