Android: Notifee.getInstance() error after app is restarted and running in background

[anderpaz]

I have the following error when the phone is restarted and the application goes up.

java.lang.NullPointerException: Attempt to invoke virtual method 'void app.notifee.core.Notifee.getDisplayedNotifications(app.notifee.core.interfaces.MethodCallResult)' on a null object reference

When method of the NotifeeApiModule class that calls Notifee.getInstance()

React-native: 0.75
@notifee/react-native: 5.7.0

Has anyone had this problem that can help me?

First thing I'm doing in the app is creating a channel and when I restart the app and run a background service I get this error, which is the same reference as the one above

Hi there, I've not seen this before but it seems to be trying to create a channel... where do you attempt to create a channel in your app?

There may be something we can do to prevent the exception in the native code Notifee.createChannel, but it does seem weird the react activity isn't available when you try to call createChannel

@anderpaz can you please provide some way of reproducing this error? It's not very clear why this could be happening, and like I said above you are the first person to report this.

fix to prevent the error is release d in 7.2.0
