Providers from the BrowserModule have already been loaded


Product Progress® Telerik® Reporting
Report Viewer Native Angular Report Viewer


I have integrated the Native Angular Report Viewer in the project and it builds successfully, however, upon loading the page with the viewer it remains blank and there is an error in the browser's console.

Steps to Reproduce

The issue reproduces when the module of the Native Angular Report Viewer - ReportingAngularViewerModule, is not loaded in the root module of the Angular application but is instead imported someplace else.

Error Message

Error: Providers from the `BrowserModule` have already been loaded. If you need access to common directives such as NgIf and NgFor, import the `CommonModule` instead.

Suggested Workarounds

The only workaround, currently available, is to Import the ReportingAngularViewerModule in the root module of the Angular application which by convention is the AppModule class defined in app.module.ts:

import { ReportingAngularViewerModule } from '@progress/telerik-angular-native-report-viewer';

    declarations: [
    imports: [
    providers: [],
    bootstrap: [AppComponent]
