Could it be something to do with the syntax of

a[href="#${id}"]
Enter fullscreen mode Exit fullscreen mode

In the docs is says that if

.querySelector()
Enter fullscreen mode Exit fullscreen mode

does not find the selector it returns null.

The Document method querySelector() returns the first Element within the document that matches the specified selector, or group of selectors. If no matches are found, null is returned.

Im the video I see he wraps

a[href="#${id}"]

In backticks like this

`a[href="#${id}"]`

That might be it.
