title: Azure APIM why am i getting response code of 0
body: <p>I have an APIM setup which is backed by a logic app which puts a message into a queue.
  When I look in Application insights I can see non-successful requests being returned.</p>
  <p>All I the detail I can see  get in the response code is <code>0 [not sent in full (see exception telemetries)]</code></p>
  <p>I have a support request open with MS around why I can query the APIM directly (which means I can't see more detail of the exception)</p>
  <p>Under what scenarios should I expect to see a status code response of 0.</p>
