The title says it all. I call reload() on a user and everything works fine until I disable the user in the Firebase Authentication console. The next reload() call bombs out.

Please add the output of flutter doctor -v.

There error output seems to be missing the information about the thrown exception (probably before the part that you posted.

Please also post the code that causes this exception.

@zoechi Sorry the copy-paste got cut short. But there was only one more line of exception - I've added #10 to the snippet above. And added two more lines of my own logging just to show that there was nothing else.

code:

        try {
        user.reload()
          .then((_) {
            if(user.isEmailVerified) {
              timer.cancel();
              updateScratchField(user.uid, 'emailVerified', true);
            }
          })
          .catchError(() => logout());
        } catch (_) {
          logout();
        }

try {} catch {} was added as a futile attempt at catching this exception. Basically the whole code is a futile attempt to synchronise emailVerified status from Firebase Auth to my own Firestore database. I'm polling from a Timer.periodic() until I see the emailVerified then stop the timer and update a field in my database. But instead of verifying email I disabled the user while testing and got this.

The "issue" it report doesn't seem like an issue (deployment to iOS works) and not related to this problem.

Tried to upgrade to firebase_auth 0.7.0 (tip of the master, actually) which is not released yet. Same results.

[kroikie]

Hi @kika looks like on Android this exception is not caught. Did you try this on Android and iOS and if so what were the results? Did it fail on both?

[kika]

I'm no longer having this issue on iOS or Android. Instead of assert exception i'm getting correct PlatformException(ERROR_USER_DISABLED, The user account has been disabled by an administrator., null)

firebase_auth: ^0.8.4+5
