PH40653: HTTP status code changes from 400 to 500 when response codes are mapped.

APAR status

• Closed as unreproducible in next release.

Error description

• When an IMS service provider API receives data that exceeds the
  field length, the following is reported:
  
  HTTP status code 400
  {    "errorMessage": "GMOSR0013E: An unexpected error occurred
  processing service XXX_svc using trancode ZZZZ.  Originating
  exception message = GMOMW0005E: A data type conversion error
  occurred while the leaf field AAAA.BBBB of service interface
  XXX_svc_Req was converted: IWAA1111E: String
  TRACE12341234354646467567868678768678122334 exceeds maximum
  length of 32.."
  }
  
  When response codes are mapped and the same data are sent, the
  HTTP status code reported is different and the following is
  reported:
  
  
  HTTP status code 500
  {    "errorMessage": "BAQR7033E: Internal server error."
  }
  
  And then following messages are written to the messages.log:
  
  GMOMW0005E: A data type conversion error occurred while the
  leaf field AAAA.BBBB of service interface XXX_svc_Req was
  converted: IWAA1111E: String
  TRACE12341234354646467567868678768678122334 exceeds maximum
  length of 32..
  GMOSR0013E: An unexpected error occurred processing service
  XXX_svc using trancode ZZZZ.  Originating exception message =
  GMOMW0005E: A data type conversion error occurred while the leaf
  field AAAA.BBBB of service interface XXX_svc_Req was converted:
  IWAA1111E: String TRACE12341234354646467567868678768678122334
  exceeds maximum length of 32..

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the z/OS Connect EE V3.0 IMS    *
  *                 service provider.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: HTTP status code changes from 400 to    *
  *                      500 when response codes are mapped.     *
  ****************************************************************
  When response mappings were present and a HTTP status code was
  returned  for which there was no specific mapping the processing
  of the response resulted in a subsequent error, which caused the
  HTTP status code 500 to be returned.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect EE has been changed to prevent the reported
  difference in behavior when a field length is exceeded.
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect EE V3.0.61.0 (PH48652).
