Type '{}[]' is not assignable to type 'AngularFireList<any[]>'

Question

I'm new with Angular and Firebase, I'm trying to get all of my items of a node to an AgularFireList, but I get this error:

Type '{}[]' is not assignable to type 'AngularFireList'. Property 'query' is missing in type '{}[]'.

My code is:

my_notes: AngularFireList<any[]>;

constructor(public afDB: AngularFireDatabase) {
    this.getNotes()
      .subscribe(
        notas => {
          this.my_notes = notas;
        }
      );
  }

  getNotes(){
    return this.afDB.list('/notas').valueChanges();
  }

Thanks for the help.

Answer 1

Try this:

constructor(public afDB: AngularFireDatabase) {
this.getNotes()
  .subscribe(
    (notas: AngularFireList<any[]>) => {
      this.my_notes = notas;
    }
  );
}

If the issue still persists, try also adding this bit of code:

getNotes(){
    return <Observable<AngularFireList<any[]>>>this.afDB.list('/notas').valueChanges();
  }
