cancelled:layerview-create error in view.whenLayerView()

[Ma1h]

I have the following code to create and load a GraphicsLayerView. When the user navigates away from the tab while the map is rendering, which triggers ngOnDestroy() to destroy the mapView, it receives the cancelled:layerview-create error. Can this error be safely ignored or there's a better way to handle it? Thanks.

const func = () {
    const subject$ = new Subject<void>();
    this.layer = this.service.createGraphicsLayer().layer;
    this.service.loadGraphicsLayer(this.map, this.layer).subscribe(() => {
      this.mapView.whenLayerView(this.layer).then((lv: __esri.GraphicsLayerView) => {
        this.layerView = lv;
        subject$.next(void 0);
        subject$.complete();
      })
      // .catch(error => {
      //   if (error.name !== 'cancelled:layerview-create') {
      //     throw error;
      //   }
      // });
    });
    return subject$;
}
