Object is possibly 'undefined'.

[sultanmyrza]

By following this guide I'm trying to call my function when the user finishes the tutorial but got Object is possibly 'undefined'. error

Got the same error. Angular 12.0.3

Solution found by going to tsconfig.json and setting strict: false

A better way to solve this would be to subscribe to the event in the component class in the ngAfterViewInit() lifecycle hook:

@ViewChild(JoyrideDirective) joyride: JoyrideDirective;

sub: Subscription;

ngAfterViewInit() {
    this.sub = this.joyride.done!.subscribe(_ => captureWithCustomCamera());
}

ngOnDestroy() {
    this.sub.unsubscribe();
}
