[Resolved] I'm getting an error with some ajax requests

I am trying to: Configure a plugin calls Smush Pro. Tha plugin performs an ajax request and that request triggers an error when I see the logs the error below is shown.

Link to a page where the issue can be seen: It is in the admin panel.

I expected to see: No errors:

Instead, I got: This error, see this video for more information: hidden link
