Sorry, I couldn’t reproduce your issue yet. From your screen recording, did the response originally have a second example before you deleted the first one? Please confirm and feel free to provide more details if needed.
Interesting - this only appears on the duplicated version and not the original, it appears that it’s not quite what I thought it was, duplicating removes the example from the 500 response and moves it to an exception on the success response
So when you then delete the success example the exception example becomes the new success example, but you’d expect the exception example to carry over as the 500 server error’s example if that makes any sense at all
