<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">We also see this. Consumers often confuse it as a problem with the api gateway rather than the upstream app. I think this also leaks too much internal detail
out to the public side, which is the kind of thing that gets flagged up on security audits. The option to return a simple 503 return status to the browser with the more detailed error sent to the log would be great.<o:p></o:p></span></p>

on how to diagnose it?<o:p></o:p></p>

<p class="MsoNormal">Right now, when the APIMAN gateway cannot connect to the API implementation's endpoint, the response code is 500, the message is null, and there is a stack trace. It's not a very useful response for the caller, and it's not really an internal
problem with the gateway. It would be better if another response code were used (502? 503?) and a useful message were returned instead of a stack trace.<o:p></o:p></p>
