Description
Describe the bug
I tried to implement anonymous sign-in feature, such as:
initialize() async {
_auth.onAuthStateChanged.listen(_onAuthStateChanged);
_user = await _auth.currentUser();
if (_user == null) {
await _auth.signInAnonymously();
} else {
_user.reload();
}
}and ended up with await _auth.signInAnonymously(); throwing the error below. (note that it doesn't contain any useful error code, message etc.)
flutter: PlatformException(ERROR_INTERNAL_ERROR, An internal error has occurred, print and inspect the error details for more information., null)
After hours of debugging, I finally figured out that I haven't turned anonymous sign-in method on at Firebase console. Yes, it was a silly mistake but it would've been caught much much faster if the error message contained ERROR_OPERATION_NOT_ALLOWED, as documented.
I believe this lack of information is not an intended behavior.
To Reproduce
I'm not sure it's method-specific situation or just an general issue. In my case, it was caused when I tried to call signInAnonymously with the related setting off.
Expected behavior
Error message contains proper error code and message.
