Error: Unexpected value 'undefined' imported by the module

Question

I\'m getting this error after migrating to NgModule, the error doesn\'t help too much, any advice please?

Error: Error: Unexpected value \'undefined\' import         


        

Answer 1

Another reason could be some code like this:

import { NgModule } from '@angular/core';
import { SharedModule } from 'app/shared/shared.module';
import { CoreModule } from 'app/core/core.module';
import { RouterModule } from '@angular/router';
import { COMPANY_ROUTES } from 'app/company/company.routing';
import { CompanyService } from 'app/company/services/company.service';
import { CompanyListComponent } from 'app/company/components/company-list/company-list.component';

@NgModule({
    imports: [
        CoreModule,
        SharedModule,
		RouterModule.forChild(COMPANY_ROUTES)
    ],
    declarations: [
		CompanyListComponent
    ],
    providers: [
		CompanyService
    ],
    exports: [
    ]
})
export class CompanyModule { }

Because exports is empty array and it has , before it, it should be removed.
