JSON Error

I am trying to get the link from the image to show in a different part of the page. On first upload it doesn’t work and I get this error :

JSON.parse(document.getElementById(‘wpforms-59-field_39’).value)[0].url;

However, if I reupload again my code works like a charm. I am not sure if I should set a timeout. Any info would be great:

Here is the js that grabs that url:

var parsed = JSON.parse(document.getElementById(‘wpforms-59-field_39’).value)[0].url;

console.log(parsed);

The page I need help with: [log in to see the link]
