Crash app when receive a notification in background

[TalesMattos]

When I subscribe to a topic and then the app goes to the background, when a new notification is received, the app crashes.
I am using Ionic 4 with Capacitor v2 and plugin version 1.1.2 (the latest for Capacitor 2) on Android 13.

see the log when the app crashes:

ERROR:

Could you guys fix it to work on Android 31 and above? Thanks!
