React Native - RCTFatalException: Unhandled JS Exception: "version" is a required argument

I'm doing a React Native App

(react-native: 0.43.4)

And I'm having problems on running Release schema on iOS.

I have Pods (Crashlytics) and I'm running my app through the Workspace Project.

On Debug schema it runs without a problem, when I switch to Release it throws this exception:

*** Terminating app due to uncaught exception 'RCTFatalException:

I've been searching this exception although I haven't find a solution yet...

Any clue what this is?

Thank you.
