Prerendering failed because of error

I am using Visual studio 2017 for asp.net 2.1 angular spa template with server side rendering.
following is the codes in package.json:

codes in app.module.ts

@NgModule({
declarations: [
AppComponent,
NavMenuComponent,
HomeComponent,
CounterComponent,
FetchDataComponent
],
imports: [
BrowserModule.withServerTransition({ appId: 'ng-cli-universal' }),
SharedModule,
RegModule,
HttpClientModule,
AlertModule.forRoot(),
AppRoutingModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

the project works fine in development mode. The publishing with visual studio 2017 finished without error. However After I moved the published files to the IIS server. The project could not start.

Following is the error message in log:

Microsoft.AspNetCore.NodeServices.HostingModels.NodeInvocationException: Prerendering failed because of error: C:\web1\ClientApp\node_modules\ngx-bootstrap\pagination\pagination.component.js:1

When I remove the ngx-bootstrap from the project, the project works fine on iis server. It seems an issue from ngx-bootstrap. It would be appreciated if you can help me to fix the issue.

a correction: in the app.module.ts I used PaginationModule.forRoot() not AlertModule.forRoot()

I can confirm that I have this issue also. Using identical versions of Angular, NGX-Bootsrtap 3.0.1, and Bootstrap 4.1.1. However this is working in a different ssr project that doesn't use the default template, and is in fact using angular 6. I simply created my own pagination component for the angular 5 spa template, so not really an issue for me, just thought I'd mention it.
