TypeError: Cannot read property 'scrollIntoView' of null How to solve?

const ref = useRef(null);

const executeScroll = () => {
        ref.current.scrollIntoView({ block: 'end', behavior: 'smooth' })
    }

    useEffect(() => {
        executeScroll()
    }, [])


<div className="comment" ref={ref}>
//Data
</div>

I am trying to go to a particular div. I got this error. Any idea why is this error is showing or how to solve it?

When the useEffect runs, the div hasn't mounted to the DOM yet so the ref is still null.

useEffect(() => {
  if (ref.current) {
    executeScroll();
  }
}, [ref.current])
