🐛 [firebase_storage] ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception

[yanivshaked]

Generally speaking, downloading works. But, from time to time while downloading from firebase storage, the following error message is omitted (on Android) and download stops. I'm unable to further download other files from firebase storage until I restart the application.

[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(firebase_storage, length=11; index=11, {}, null) E/flutter ( 8185): #0 StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:581:7) E/flutter ( 8185): #1 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:158:18) E/flutter ( 8185): E/flutter ( 8185): #2 new MethodChannelTask.

[markusaksli-nc]

Hi @yanivshaked Is this specific to some type or size of files? Thank you

[yanivshaked]

No, and the same file might be downloaded ok or failed on different sessions.

[yanivshaked]

Following information from crashlytics shows the problem. I have provided illegal URL. Still, I would expect an error value returned rather than an unhandled exception.

[russellwheatley]

Hey @yanivshaked, are you able to provide a reproducible sample for this error? It appears that the error is fatal, and coming from the platform. In that case, there is nothing Flutterfire can do to catch the exception. This indicates a problem with the underlying Firebase SDK. Either way, it is hard to judge without a reproducible sample.

[yanivshaked]

Hi @russellwheatley, Sorry, but I'm unable to provide a reproducible sample for that error (that project is no longer on focus). As I wrote on my first message, this error is not persistent (doesn't happen every time) but happens from time to time. I believe this issue can be reproduced by trying to download a file from firebase storage and if it works, restarting the application and downloading again - until it fails. Sorry I can't provide any more relevant information or a reproduction sample.

@russellwheatley Hi, it looks similar to https://github.com/firebase/flutterfire/issues/3862 and fix to it was https://github.com/firebase/flutterfire/issues/3862#issuecomment-833578129, so does the same needed for this issue too ?

[russellwheatley]

I think given how stale the issue is, we ought to close it out.
