Answer 1

I looked in the browser console (F12 - Chrome) in the network tab, on the page where the Internal Server Error occurred and saw what the error was exactly.

As the function comes from an ajax request the error is not shown in the console or in the PHP error. Only error 500 is shown. In the tab shows the language error, which in my case php, and was the lack of a Procedure to run the method of creating html for the screen.
