Monitoring not working for me

Appflow
1

My code:

import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule, Injectable, Injector } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { Pro } from '@ionic/pro';


Pro.init('d84aec69', {
  appVersion: '0.0.1'
})

@Injectable()
export class MyErrorHandler implements ErrorHandler {
  ionicErrorHandler: IonicErrorHandler;

  constructor(injector: Injector) {
    try {
      this.ionicErrorHandler = injector.get(IonicErrorHandler);
    } catch(e) {
      // Unable to get the IonicErrorHandler provider, ensure
      // IonicErrorHandler has been added to the providers list below
      this.handleError(e);
      console.log(e);
    }
  }

  handleError(err: any): void {
    Pro.monitoring.handleNewError(err);
    // Remove this if you want to disable Ionic's auto exception handling
    // in development mode.
    this.ionicErrorHandler && this.ionicErrorHandler.handleError(err);
  }
}

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: MyErrorHandler}
  ]
})
export class AppModule {}

I remove IonicErrorHandler from providers to catch the error

Output from console:

Ionic Pro initializing (app id: d84aec69)
main.js:sourcemap:133 Error: StaticInjectorError[IonicErrorHandler]:

    at new MyErrorHandler (main.js:sourcemap:127)

Maybe I miss something or not understanding the concept.

Any help? Thanks!

Ok. Solved…

There is no error with code at all. Its only that this errors are not in realtime.

Maybe you can get an exception and it appears 1 hour later on the web.

This is normal?

Thanks
