[🐛] Crashlytics not reporting crash in Debug and not honouring setCrashlyticsCollectionEnabled

[nmehlei]

Issue

Firebase Crashlytics does not actually crash when invoking crashlytics().crash() and no crashes are being reported in Firebase's Crashlytics dashboard.

In our case, Firebase.json does indeed disable firebase (see snippets below), yet this is being enabled via setCrashlyticsCollectionEnabled() after app start. This needs to be opt-in due to GDPR compliance, yet based on logs this is confirmed to be enabled almost instantly after app start.

Our full initialization code looks as follows:

public async initialize(): Promise<void> {
    return new Promise<void>(async (resolve, reject) => {
        let crashReportingEnabled = environment.crashReporting.enabled;

        if(!crashReportingEnabled)
            this.logger.info('Crash reporting is disabled based on configuration');

        await crashlytics().setCrashlyticsCollectionEnabled(!crashReportingEnabled);

        if(await crashlytics().didCrashOnPreviousExecution()) {
            console.warn('Crashlytics reports that the app crashed on a previous execution');
        }

        if(await crashlytics().checkForUnsentReports()) {
            if(crashReportingEnabled) {
                crashlytics().sendUnsentReports();
                this.logger.info('Sent previously unsent crash reports');
            } else {
                this.logger.warn('There are unsent crash reports that cannot be sent since crash reporting is disabled');
            }
        }

        resolve();
    });
}

The issue happens for both Android & iOS. In the case of iOS, the crashlytics-related logs show that Firebase assumes it is disabled, hence it somehow does not seem to make use of the setting above. Also, yes, I did run pod install after firebase.json change.

I don't reproduce this - I just added some infrastructure in our e2e app specifically to re-enable crash testing after our migration of the e2e app to New Architecture. It works for me.

https://invertase.io/blog/react-native-firebase-crashlytics-configuration is the integration and testing process walk through

To see what I see:

git clone [email protected]:invertase/react-native-firebase
cd react-native-firebase
yarn
yarn lerna:prepare
yarn tests:android:build && yarn tests:ios:pod:install && yarn tests:ios:build
yarn tests:emulator:start # note this will consume one terminal
yarn tests:packager:jet # note this will consume one terminal
yarn tests:android:test # at any point while it's running, hit one of the two crash buttons
yarn tests:ios:test # at any point while it's running, hit one of the two crash buttons

Please see if that works for you
