React Native app crashes when login

I'm having troble with my app, this app is react native and everything is works well, but in production it's crashes on login. On Dev mode, on my phone it's okay, only on production crashes.

I tried some solutions that I found here in stackOverflow but none of them helped in fixing the bug. The first error is a normal firebase connection and get uid for user. I can't fix this and it's a simple connection... help please!!

This is the error:

com.facebook.react.common.JavascriptException: null is not an object (evaluating 'l.currentUser.uid'), stack:
