Getting "Unhandled JS Exception: Native module cannot be null" Error on IOS runtime with React Native

Preparing a medium size production level app for IOS.

App uses a lot of native capabilities and and some point of attempting to integrate some of them I moved to using Cocoapods.manually using a Podfile file.

This helped me to over come all the build fails and could finally get the RN app running.

Only now, getting a very vague error:

Unhandled JS Exception: Native module cannot be null

Having a hard time to figure out which 3rd party package is causing this..a bunch of git issues are pointing to add the right package to Podfile file and pod install which I did, but still not joy.

Those are the `git issues, most of them in a specific package:

• SO answers for 'react-native-push-notification'
• Git issue in 'react-native-tab-view'
• Git issue in 'react-native-push-notification'
• Git issue in 'react-native-vector-icons'
• Git issue solution

Most of those pretty much solve this the same way by adding to Podfile file the right pod link and running pod install - this did not worked for me

Things that I've tried:

• Removing binary links but JavaScriptCore.framework and libPods-myProjectName.a
• Clearing Libraries from all .xcodeproj packages to resolve duplicated linking
• Cleaned project rebuilt, cleared packages with pod deintegrate and reinstalled.. basically cleared and reinstalled everything I could
• Upgrade react-native from 0.58.6 to 0.59.9

Followed this blog post to convert my existing project to use Cocoapods`

Pod install seems pass without any errors - pod install output:

My current env:

   React: 16.6.3,   React Native: 0.59.9 // tested with React Native 0.58.6 too   Xcode: 11.4.1

Really having hard time to debug this one as React Native errors are not so helpful, plus probably missing something

Any Ideas how to get more info about this one?

Or how to solve it?

Help..
