Uncaught (in promise): Error: StaticInjectorError(AppModule)[options]

Question

I have a strange error. Usually (I did my googling), in this case of errors Angular specifies in square brackets which exactly module/service/provider/etc caused the problem

Answer 1

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';
