The data isn't probably available immediately that's why it's returning a null data. However, you can set the data asynchronously using a setTimeout delay like so.

const [price, setPrice] = useState<number>(0)

options = {
  plotOptions: {
    series: {
      point: {
        events: {
          mouseOver: function(e:any) {
            price = // logic to fetch price based on mouse position 
            setTimeout(() => { // This is where the delay comes in
            }, 0)


My hunch is there is a time delay to get that data back to you. Try async/await and then set your state back on those results.
