Uncaught TypeError: Failed to construct 'URL': Invalid URL

[markhorsman]

For some reason our implementation of the editor only works on localhost. In production or test domain we get an error in https://editor.unlayer.com/embed.js?2 on the following line:

n = (i = new URL(document.currentScript.src)).href.substring(0, i.href.lastIndexOf("/") + 1), I think document.currentScript is null for some reason.

Any ideas?
