IONIC 4 : content.scrollToPoint is giving an error as Cannot read property 'scrollTop' of null

Ionic Framework
1

I am using scrollToPoint as below to scroll to a specific point in my component.

@ViewChild(IonContent) content: IonContent;

this.content.scrollToPoint(0, yOffset - 70, 1000);

But it is giving an error like

ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'scrollTop' of null TypeError: Cannot read property 'scrollTop' of null

Can anyone please suggest me anything on this?
