Good morning, 

I'd like to know how Apiman handles errors coming from the APIs.

I have Rest web Services, a ESB and Apiman on the top, no matter what  the error generated by the Rest web service (404, 416, 412...) , Apiman always displays an error code 500. 

Why Apiman behaves this way? How can I have on apiman the same error codes as those generated by the web service?

Thank you
