Cannot read properties of null (reading 'getBoundingClientRect')

I think this happens if the the element is not ready in getSliderInfo()

quick fix:

var getSliderInfo = function getSliderInfo() {
var sl = sliderRef.current;
// --------------------------------
if(!sl) return null // fix issue if sliderRef isn't yet registered with the element
//----------------------------------
...

then we need to ignore the info if it's null from above

var updateSliderValue = function updateSliderValue(event, eventType) {
...
...
// --------------------------------
var info = getSliderInfo();
if(!info) return
// --------------------------------
...
