🐛 [REMOTE_CONFIG] `null check operator used on a null value` while calling `setConfigSettings` #12496

Closed Beyga closed 4 months ago

Beyga commented 7 months ago

Bug report

I am getting the null check operator used on a null value while calling setConfigSettings on Flutter Web.

Code:

void main () {
  WidgetsFlutterBinding.ensureInitialized();
  await FirebaseCoreWeb().initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  final remoteConfig = FirebaseRemoteConfig.instance;

  await remoteConfig.setConfigSettings(
    RemoteConfigSettings(
      fetchTimeout: const Duration(minutes: 1),
      minimumFetchInterval: const Duration(hours: 1),
    ),
  );

  await remoteConfig.fetchAndActivate();
  final remoteConfigKey = remoteConfig.getString('landing_page');

  runApp(MyApp(remoteConfigKey: remoteConfigKey));
}

Steps to reproduce

I cannot reproduce it in my local environment, it happens only on the deployed version on Firebase Hosting. Local release mode works fine too.

Thanks for the report, can you try to force refresh the Service Worker, to make sure that something isn't being cached weirdly by Firebase Hosting?

Beyga commented 6 months ago

@Lyokone It does not help. I've deleted all application data from the browser, issue persists.

Lyokone commented 6 months ago

Hello @Beyga, we have completely overhauled our JS interop recently, can you see if you are still experiencing this issue using the latest versions? Thanks

google-oss-bot commented 6 months ago

Hey @Beyga. 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!

klivin commented 6 months ago

I am experiencing this behavior, but only in my deployed codebase via flutter web. I can run locally, and Remote Config appears to work. Please advise

I'm running: firebase_remote_config: ^4.4.2

Beyga commented 5 months ago

Sorry for the late response. The issue seems to be still valid.

TarekkMA commented 5 months ago

Hello @Beyga, I've tested the current example app and it works without any issues.

You can check it out here:

https://github.com/firebase/flutterfire/blob/master/packages/firebase_remote_config/firebase_remote_config/example/lib/home_page.dart#L35

Could you try running the example app to see if you experience the same issue?
