I have integrated Firebase app check with version : firebase_app_check: ^0.3.0+4 , My flutter version is Flutter (Channel stable, 3.29.3, on macOS 15.3.1 24D70 darwin-arm64, locale en-IN). And environment:
sdk: ">=3.5.4 <4.0.0" . I am using xcode 16.2 for mac OS 15.3.1 (24D70). I had create new iOS app on firbase and configure firebase_options.dart and firebase_json.dart with correct bundle id and new GoogleService-Info.plist file replaced ffrom firebase console.

Stilll getting flutter: error [firebase_app_check/unknown] The operation couldn’t be completed. Too many attempts. Underlying error: The operation couldn’t be completed. The server responded with an error: flutter: - URL: https://firebaseappcheck.googleapis.com/v1/projects/torch-social/apps/1:858584873764:ios:e716d88ed9ac919fdbd1b1:exchangeDeviceCheckToken flutter: - HTTP status code: 400 flutter: - Response body: { flutter: "error": { flutter: "code": 400, flutter: "message": "App not registered: 1:858584873764:ios:e716d88ed9ac919fdbd1b1.", flutter: "status": "FAILED_PRECONDITION" flutter: } flutter: } error.
Can you please let us know what is wrong that needs to correct for get Appcheck token without error.

My code :

await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

await FirebaseAppCheck.instance.activate(
appleProvider:
kDebugMode ? AppleProvider.debug : AppleProvider.appAttest,
androidProvider:
kDebugMode ? AndroidProvider.debug : AndroidProvider.playIntegrity);

await FirebaseAppCheck.instance.setTokenAutoRefreshEnabled(true);
final result = await FirebaseAppCheck.instance.getToken();

getToken method give 404 error always i have changed my appattest-environment to production also

Reproducing the issue

await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

await FirebaseAppCheck.instance.activate(
appleProvider:
kDebugMode ? AppleProvider.debug : AppleProvider.appAttest,
androidProvider:

Hi @bonisha-mandora, have you registered your app to use App Check in Firebase console?

I am facing a similar error:

Error getting App Check token; using placeholder token instead. Error: Error Domain=com.google.app_check_core Code=0 "Too many attempts. Underlying error: The operation couldn’t be completed. The server responded with an error.

- HTTP status code: 403 
 - Response body: {
  "error": {
    "code": 403,
    "message": "App attestation failed.",
    "status": "PERMISSION_DENIED"
  }

I've initialised it in flutter app like:

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

FirebaseAppCheck.instance.activate(
    androidProvider:
        kDebugMode ? AndroidProvider.debug : AndroidProvider.playIntegrity,
    appleProvider: kDebugMode ? AppleProvider.debug : AppleProvider.appAttest,
);

I've done the following:

1. Enabled both Device Check and App Attest in firebase console
2. Added Firebase App Check Debug Token from XCode logs in Firebase console under AppCheck -> iOS App.
3. Added -FIRDebugEnabled argument in schemes for Arguments Passed on Launch.
4. App store connect with the device check enabled in identifiers.
5. Added App Attest capability in Xcode signing & capabilities > Runner.
6. Running on physical iOS device
