I am having the below error

Below is my background message handler

Does anyone know how to resolve this error? Thanks in advance!

I'm not sure this is an error.

This exception appears to me when the app is closed and I invoke the setup method when there is no activity present.

Maybe I'm wrong, but the setup method can't work without the activity and it should not be called from the background handler of Firebase.

Thanks for the reply. I found out where was the issue. I had changed the name of the app and the calling accounts permission in the setting has to be changed too. Once I enabled the calling accounts permission, the error does not appear anymore.

Thanks!
