Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS Connect EE V3 API          *
  *                 requesters.                                  *

  * PROBLEM DESCRIPTION: HTTP status code 500 is returned when   *
  *                      an API requester sends an empty request *
  *                      body.                                   *
  ****************************************************************
  When an empty request body was sent while invoking an external
  API, the Content-Type was set to asterisk/asterisk for the
  request body sent by z/OS Connect EE. If the endpoint is
  expecting to receive Content-Type "application/json" the
  endpoint might return the reported 500 HTTP status code.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect API requester and build toolkit has been updated to
  accept Content-Type for empty requests and pass the configured
  Content-Type to endpoint.
  
  The following build toolkit parameters have been added to
  configure the Content-Type for empty body requests:
  sendContentTypeForEmptyBody
  contentTypeForEmptyRequest
  
  This fix is available with Build Toolkit version 1.10 and above.
  
  The fix for this APAR is expected to be delivered by the PTF
  for z/OS Connect EE V3.0.60.0 (PH48008).
