Error after updating Cordova SDK to 4.0.0

And now I checked iOS as well and the app doesn’t even start. It builds successfully but the simulator is just blank. 

This is the log from XCode:

Now I see that from 3.0.0 there are breaking changes in the code in case someone already implemented version 2.x.x, so I have to update the code according to this https://github.com/RevenueCat/cordova-plugin-purchases/blob/main/CHANGELOG.md

Can please someone confirm that I am right? :)
