[Question]: Why is there an issue in intialize or other things from react-native-onesignal saying appId as null value! The app is working fine in previous released version and current debug builds, but having issues in release builds

How can we help?

Please let me know how to resolve or what can I do to for the below OneSignal errors logged on Crashlytics :-

Hi @rd273001 thanks for reporting these stack-traces.

What version of react-native-onesignal are these crashes reported for?

Crash 1: Crash when adding notification click listener:
When and how are you adding the notification click listener? This trace looks like it is happening on a background thread and SDK initialization may be happening on another thread and not finished?

Crash 2: appId is null
It looks like OneSignal.initialize(appId) is being called with null app ID. Can you confirm you are always passing a valid non-null string app ID to this initialization method?

Crash 3: Unable to destroy activity
Is this the full stacktrace? I don't see any references to OneSignal classes so I don't know where this is originating from. Do you have any more information on this crash?
