App crashes when calling getAlbumsFromArtist method

As written on the title, the app crashes when the method get called. I'm using GetX state management and calling this method every time the activeArtIdx has changed.

playlist_controller.dart

class PlaylistController extends GetxController {
  static PlaylistController get to => Get.find();

  final _query = FlutterAudioQuery();
  final artists = <ArtistInfo>[].obs;
  final activeArtIdx = 0.obs;
  final albums = <AlbumInfo>[].obs;
  final activeAlbIdx = 0.obs;

  @override
  void onInit() {
    _fetchArtists();
    ever(activeArtIdx, _fetchAlbums); // call _fetchAlbums every time activeArtIdx is changed.
    super.onInit();
  }

  Future<void> _fetchArtists() async {
    final ars = await _query.getArtists(sortType: ArtistSortType.DEFAULT);
    final invalidChars = RegExp(r'.*[\\\\/:\"*<>;|].*$');
    final filtered = ars.where((ar) => !ar.name.contains(invalidChars));
    artists.assignAll(filtered);
  }

  // this crashes the app.
  Future<void> _fetchAlbums(int artIndex) async {
    final a = await _query.getAlbumsFromArtist(artist: artists[artIndex].name);
    a.forEach((alb) => print(alb));
  }
}
