Troubleshooting error 500

I am trying to find the error on a page. Error reporting is on for Server Connect. When I run the API Server Connect file in the browser it works 100%. When calling it from the front end(App connect) I get a error 500. Here are screenshots of what I see in Dev Tools:

Could the error be caused by the serverConnectform.js file? Could there be an update to this file that is out of sync with the serverconnect action file?

Check the following article:
Debugging Server Connect Errors
Here it’s explained how to debug server connect errors.

Thanks - that is exactly how I do it and normally I get a error explanation like this in example:

9eddce7084b54884d31d0928d73a34861970fd73_2_690x384

But All I get is the :error trying to load resource" and not further explanation.

File is uploaded and the form calls it ons submit, but something goes wrong.

Please provide a link where we can check what’s wrong. Also, is the detailed error reporting enabled on your server?

Ok, will first check out detailed error reporting - that might be the issue. Will PM you details if it is and I still can’t win. Thanks
