I have a project with hundreds of image files. I was hoping to use "AJAX On Error" event to detect if a file with a specified name exists. However, instead of triggering this event, AJAX throws an exception in console log.
Steps to reproduce
Add AJAX request with a non-existing filename:
Observed result
Expected result
I expected AJAX On Error to trigger.
