React Native 0.59 -> 0.60 - Unable to resolve module `NativeModules` - react-native

Question

I want to make sure that my native library works on 0.6x React Native. I've got a version of the library working on 0.59.x but when I run it on 0.6x I get the following json response (together with server 500):

So my quetion is: How is it possible that the NativeModules were "visible" in previous version? All I did was upgrade the react native version and left all the code as it was.
It still works on 0.59.
