Solution to “NullInjectorError: No provider for module” in Angular 9

in Angular on May 16, 2020

The error occurs because of missing providers in app.module.ts

The error mostly occurs when we try to change one of the services and class and forget to update the providers in the app.module

Just add the missing providers and the error will go away.

Look at this code:


@NgModule({
  imports: [
    BrowserModule,
    ...OtherModules...
  ],

  providers: [blah..blah...blah],   //<-- add your missing providers here

  bootstrap: [ AppComponent ]
})
export class AppModule {}
