Description

I expected to get a token, and it keeps giving an error in console.

Reproducing the issue

A flutter app with App Check and try to get the token.

Example:

WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

await FirebaseAppCheck.instance.activate(
webProvider: ReCaptchaV3Provider('KEY_HERE'),
androidProvider: AndroidProvider.debug,
appleProvider: AppleProvider.deviceCheck,
);

print(await FirebaseAppCheck.instance.getToken());

runApp(MyApp());
}

Firebase Core version

Hi @Kugyan, I'm unable to reproduce this issue with the firebase_app_check example app. Can you provide a minimal repo I can clone to reproduce this issue?
