No pushNotification and badge counter on Android

[websystemtechnology]

From my Android version 12, when I get a notification on my app I get this error:

AndroidRuntime: FATAL EXCEPTION: Firebase-Messaging-Intent-Handle AndroidRuntime: Process: package_app, PID: 23149 AndroidRuntime: java.lang.IllegalArgumentException: package_app: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. AndroidRuntime: Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

How can I solve the problem?
