This shouldn’t be used - it’s an ancient version and lacks a lot of recent fixes. Your issue is this:

You’re using some kind of server side rendering to render the endpoint. For example, if you’re rendering the page that you’ve set as the endpoint using a serverless function, you’d not seem the submission in the UI. The solution is similar, set the endpoint to a page or an asset (like /favicon.ico) that already exists.
