import { HTTPListener, HTTPStatus } from './services/RxJS/HTTPListener.service';

const RxJS_Services = [HTTPListener, HTTPStatus];


@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    FormsModule,
    RouterModule,
    AppRoutingModule
  ],
  providers: [
    ...RxJS_Services
    {
      provide: HTTP_INTERCEPTORS,
      useClass: HTTPListener,
      multi: true
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

Doesn't it suppose to have a comma after the "...RxJS_Services"?
