I'm using v5.0.5 and have the same problem. Is there any update regarding this issue?

@v12cicd I solved my problem. It seems, that the error message FATAL: OneSignal AppId: (null) - AppId is null or format is invalid, stopping initialization. has no negative effects. My problem was the buildOptimizer when building on prod configuration. Setting it to false in angular.json solved the problem.

After changing
OneSignal.Debug.setLogLevel(LogLevel.Verbose);
to
OneSignal.Debug.setLogLevel(6);
I could activate the buildOptimizer and everything works fine. Try it and let me know!

Happens for me in Capacitor with 5.1.0 as well. As mentioned here, a small timeout seems to fix it.

Anyways it has negative effects, because the subscription id is null in the sdk if this happens.

On Ionic / Angular you can add the following line before the OneSignal Plugin Initialization:

await this.platform.ready();

This also seems to fix the error!
