Cannot read properties of null (reading 'scrollIntoView')

This error occurs when you are trying to access the `scrollIntoView` method on an element that does not exist or is null.

To fix this error, you need to make sure that the element you are trying to scroll to actually exists and is not null. Check that you are selecting the correct element and that it is present in the DOM.

You can also try using a conditional statement to check if the element exists before calling the `scrollIntoView` method:

const element = document.getElementById('myElement');

if (element) {
  element.scrollIntoView({ behavior: 'smooth' });
}

This will only call the `scrollIntoView` method if the element exists and is not null, preventing the error from occurring.
