Here is the related code:

constructor(
    public platform: Platform,
    public statusBar: StatusBar,
    public splashScreen: SplashScreen,
    private motoboy: Motoboy,
  ) {

Yes, I have that class declared in providers in app.modules.ts, it successfully works without the --prod flag.

I tried to upgrade angular packages and it stacktrace mentioned AoT files, not sure what to do with it though.
