Strange one here. iOS. "nativescript-angular": "~7.1.0", "nativescript-orientation": "~2.2.1"


    private route: ActivatedRoute,
    private page: Page,
    private routerExtensions: RouterExtensions
  ) { = true;

  ngOnInit() { = this.route.snapshot.params['id'];
    orientation.setOrientation('landscape', false);

my landscape.component.html is completely empty.

the LandscapeComponent is loaded via navigation from another component. The onCreate() method is called from a (tap)="onCreate() button press:

  async onCreate() {
    try {
      const item = await this.createItem();
      console.log(`Created`, item);

      this.routerExtensions.navigate(['../landscape',], {
        clearHistory: true
    } catch (error) {
      console.error('Problem creating', error);

If I comment out orientation.setOrientation() I don't get the error.

Any ideas? FWIW it still flops the screen orientation to landscape.

The workaround I found is to add it into ngAfterViewInit() like so:

  ngAfterViewInit() {
    orientation.setOrientation('landscape', false);

Putting it in ngOnInit() will cause Zone view update problems, I think due to the Error preventing further processing. It still throws the error, so if you have other logic in ngAfterViewInit() this hack may not work for you.
