Instead of getElementById there's a good way of controlling the elements on the template by using the @ViewChild Directive. (Angular 8)
in the template adding a local reference to the button: (#photoInputButton)
in the component adding the @ViewChild directive referencing the photoInputButton:
@ViewChild('photoInputButton', {static: false}) photoInputButton: ElementRef; //{static: true} => only if it's being used in the ngOnInit phase
Now you have an ElementRef - you can trigger the click:
this.photoInputButton.nativeElement.dispatchEvent(new MouseEvent('click'));
