Error messages once a NativeScript app loads on Android

Question

after updating my app to NativeScript 5.1/tns-core-modules to 5.1.2, I am having this messages once the app starts:

I have removed the /core_modules, /hooks, /platforms/android folders and the messages are still showing.

Any clue whats going on?

Thanks!

These are only warnings and you don't have to worry about it. Still, if you are interested in what is causing them and how to (possibly) remove them, see the discussion in the opened issue here:
