Angular: Error when TypeScript object returns an array object value

I have encountered a strange issue where the array value returned as [object Set] when I console log it. It's unclear whether this problem is occurring in the component or the service, but the object values are not being displayed.

This issue arises when the deleteRow function is called from the component and passed to the service.

view.component.ts

    @Component({
  templateUrl: "viewpage.component.html"
})
export class ViewpageComponent implements AfterViewInit, OnInit, OnDestroy {
  // Component logic here
}

// trimmed for brevity

  // Delete row functionality

  deleteRow() {

    // Deletion logic goes here
  }

view.service.ts

    @Injectable({ providedIn: 'root' })
export class ActionService {
  // Service logic here
}

The result is '[object object]' because the + operator invokes the toString method of the object

An example of this is:

console.log('scope is ' + scope);
This will output the string scope is [object object]

Alternatively, use console.log() with commas to print the object directly

console.log('scope is', scope)
