title: How to update the error code in IIB for my pass thro
body: <p>I am getting 500 error code and its a SOAP format.
  I see HTML, SOAP 1.1 &amp; SOAP 1.2 formats available for response when there is an exception in my pass thro service for example when wrong endpoint request, it gives 500.</p>
  
  <p>I want to change it to 400 or 404 for invalid request/not found.
  Please advise for updating it for a SOAP/JSON response. It would be nice to know for both the format.</p>
