Angular - The argument provided is not compatible with the parameter

I encountered the following TypeScript errors in app.component.ts:

Issue: Argument of type '(events: Event[]) => void' is not assignable to parameter of type '(value: Event[]) => void'.

Description: Types of parameters 'events' and 'value' are incompatible.

Solution: Type 'Event[]' is not assignable to type 'import("/home/src/app/models/event.interface").Event[]'.

Error: Type 'Event' is missing properties like _id, name, date from type 'Event'.

Reviewing my code:

event.interface.ts

export interface Event{
    _id: string;
    name: string;
    date: Date;
}

app.service.ts

  getEvents(): Observable<Event[]> {
    return this.http.get<Event[]>('www.example.com/your-events')
  }

app.component.ts

  ngOnInit() {
    this.appService.getEvents().subscribe(
      (events: Event[]) => {
        this.promotersEvents = events;
      }
    )
  }

I'm seeking advice on what might be wrong with my code. Thank you!

Answer №1

It's possible that you may have overlooked importing the Event interface either in your app.service.ts or in your app.component.ts. This could be causing a conflict with the native Javascript Event.

If this suggestion doesn't resolve the issue, consider renaming the interface to prevent clashes with Ecmascript definition files.
