Current behavior: I try to use your latest ionic angular version which you merged yesterday with the 3.0 branch, so I’m trying to migrate my app on angular4 rc.5 By the way, I’m interested to beta test your new ionic3 with now IonicPage (DeepLink) over ionic4 👍

There are two bugs:

1. the Custom Error Handler does not work as in version 2, on declaring the provider for Custom Error Handler in app.component.ts { provide: ErrorHandler, useClass: LanthingsErrorHandler, deps: [ ToastController ] }, we get this error

polyfills.js:3 Unhandled Promise rejection: Class constructor IonicErrorHandler cannot be invoked without 'new' ; Zone: <root> ; Task: Promise.then ; Value: TypeError: Class constructor IonicErrorHandler cannot be invoked without 'new'(…) TypeError: Class constructor IonicErrorHandler cannot be invoked without 'new'

1. the other error we get is on a Custom HTTPService

export function httpFactory(backend: XHRBackend, options: RequestOptions, platform: Platform) {
  return new HttpService(backend, options, platform);
}

...
providers: [
      {
          provide: HttpService,
          useFactory:  httpFactory,
          deps: [XHRBackend, RequestOptions, Platform ]
        },

we get this error
