Running `flutterfire reconfigure` returned a `FormatException`

[Cyrille-Dakhlia]

[REQUIRED] Environment info

firebase-tools: 13.11.2

Platform: macOS

[REQUIRED] Test case

I am so sorry, I cannot find reasonable time to provide this...

[REQUIRED] Steps to reproduce

1. Have a Flutter project configured with flavours (eg. staging, production)
2. Configure Flutter apps (iOS and Android) with Firebase projects (eg. staging, production)

        flutterfire configure \
            --project=<redacted> \
            --out=lib/firebase/firebase_options_staging.dart \
            --android-package-name=<redacted> \
            --android-out=android/app/firebase/flavors/staging/google-services.json \
            --ios-bundle-id=<redacted> \
            --ios-out=ios/firebase/flavors/staging/GoogleService-Info.plist \
            --ios-build-config=Debug-staging,Profile-staging,Release-staging

3. Addition of Firebase aliases

firebase use --add staging.  // association to staging Firebase project
firebase use --add production.  // association to production Firebase project
firebase use staging

4. Modify main.dart file to load appropriate firebase_options.dart file

// main.dart file

void main() async {
   ...
   WidgetsFlutterBinding.ensureInitialized();
   await initializeFirebaseApp();
   ...
}

// flavor_config.dart file

import 'package:flutter/services.dart';
import 'firebase/firebase_options_production.dart' as production;
import 'firebase/firebase_options_staging.dart' as staging;
import 'package:firebase_core/firebase_core.dart';

enum Flavor { production,  staging; }

Flavor getFlavor() => switch (appFlavor) {
      'production' => Flavor.production,
      'staging' => Flavor.staging,
      _ => throw UnsupportedError(
          'Invalid flavor: "$appFlavor".'),
    };

Future<void> initializeFirebaseApp() async {
  final firebaseOptions = switch (getFlavor()) {
    Flavor.production => production.DefaultFirebaseOptions.currentPlatform,
    Flavor.staging => staging.DefaultFirebaseOptions.currentPlatform,
  };
  await Firebase.initializeApp(options: firebaseOptions);
}

5. Add firebase_core package to Flutter project: flutter pub add firebase_core
6. Reconfigure project after previous addition of firebase_core: flutterfire reconfigure
7. See the result in the output log:

flutterfire reconfigure

[REQUIRED] Expected behavior

Having the Firebase configuration for current Firebase project alias selected (staging) reconfigured when running flutterfire reconfigure.

[REQUIRED] Actual behavior

• Having the following output log after running flutterfire reconfigure

This issue does not have all the information required by the template. Looks like you forgot to fill out some sections. Please update the issue with more information.

Hi @Cyrille-Dakhlia, sorry to see that you're running into this issue. My best guess right now is that there is a file permissions issue that is breaking things for you. A few things to try:

• Could you run chmod -R +x /Users/cyrilledakhlia/.cache/firebase/, and then rerun the command?
• If that does not work, is there a 'firebase-debug.log' file in your directory that you could share? If not, is there a way to pass in the --debug flag? (Unfortunately, I'm not super familiar with flutterfire and don't really now how it is invoked)

@Cyrille-Dakhlia if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

Started seeing this issue after flutterfire update Rebuilding cache by running flutter pub cache repair helped me to fix this issue
