[firebase_app_check]: Failed to create a block of data that demonstrates the legitimacy of the app instance #13377

App Check

Which platforms are affected?

iOS

Description

I am getting this crashlytics log on my live app since my users have upgraded to iOS 18 : 

[firebase_app_check/unknown] The operation couldn’t be completed. Failed to create a block of data that demonstrates the legitimacy of the app instance (`generateAssertion:clientDataHash:completionHandler:`); keyId.length = 44, clientDataHash = aaF0YVycJAh9/UwALfjjlbdTCIfxkIQZ4yqUdsLE9R0=, systemVersion = 18.0; DCErrorInvalidKey - An error caused by a failed attempt to use the App Attest key..

It seems that the code is unable to use the App Attest key to create a block of data.

I have seen some existing issues in the Firebase iOS SDK but it doesn't seem to be exactly the same as mine (per the function name and the iOS 17 users).

For me it working fine until iOS 18 since i monitor my live app more or less every day.

Reproducing the issue

I could not reproduce it locally even on my iOS 18 app in debug mode, but in release mode i have more or less 50 logs in Crashlytics since the iOS 18 release

Firebase Core version

3.4.0

Flutter Version

3.24.3

Relevant Log Output

Additional context and comments

I also see that i am using the 3.4.0 instead of 3.5.0 but i am not sure if this change includes the solution for App Check... In any case i will upgrade for my next release today and see if it's still happening

SelaseKay commented 2 months ago

Hi @Tom3652 , Did the upgrade resolve this issue?

Tom3652 commented 2 months ago

Hi ! Unfortunately not i am afraid :/

SelaseKay commented 2 months ago

Can you provide a sample code and steps to reproduce this issue?

Tom3652 commented 1 month ago

Well in my production app i only have this code : 

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

in main.dart after initializing firebase app, and i am calling : 

  try {
      appCheckToken = await FirebaseAppCheck.instance.getToken() ?? "";
    } catch (error) {
      AnalyticsAPI.logError(error, reason: "Could not fetch app check token");
    }

Where AnalyticsAPI.logError is my function that records the error in Crashlytics.

Note : i have no swift code or any custom native classes.

Foxsterc commented 1 month ago

Getting the same issues here, not all users but enough.

firebase_app_check: ^0.3.1+2

Tom3652 commented 1 month ago

Hey @Foxsterc is it also only on iOS 18 for your users ?
