How to proceed to debug a react native app?

Question

I am facing issues with my react native app and I don't know how to proceed to debug it.

I passed my time to fix mismatch between: the different versions of the packages I am using, the different upgrades/updates (packages, react native, Android Studio etc.), the dependencies more than actually code or correct my code.

It's really frustrating and I feel like I do it wrong or something to stay stuck that much with these kind of problems.

Here the informations I have concerning my current issue:

I have Messages Build Gradle :

                                                  Hint: This error often happens when you're running the packager (local dev server) from a wrong folder. For example you have multiple apps and the packager is still running for the app you were working on before.
                                                  If this is the case, simply kill the old packager instance (e.g. close the packager terminal window) and start the packager in the correct app folder (e.g. cd into app folder and run 'npm start').

                                                  This error can also happen due to a require() error during initialization or failure to call AppRegistry.registerComponent.

And the error I get on my device (which is linked to the react-native-navigation package: https://wix.github.io/react-native-navigation/#/ ):

undefined is not an object (evaluating 'NativeReactModule.startApp')

So I wonder, beyond my issue, what is the "checklist" to debug something like that ?

What is revelant ? What is not ?

Where should I research solutions first ?

PS: I already followed the hint displayed in the logcat with no success.

Thanks in advance.

这个问题是因为它找不到本地模块，因此在Android中安装react-native-navigation程序包后，您需要执行以下步骤
