PH64881: An empty object in an OpenAPI 3 payload is not processed by the z/OS Connect server.

APAR status

• Closed as unreproducible in next release.

Error description

• When the openapi.yaml for an OpenAPI 3 API project contains an
  optional object that itself has only optional properties, when
  none of the child properties are present (leading to an empty
  object) the z/OS Connect server removes the empty object.
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS Connect OpenAPI 3 API      *
  *                 requester plug-in and API provider plug-in   *
  *                 (API-First).                                 *

  * PROBLEM DESCRIPTION: An empty object in an OpenAPI 3 payload *
  *                      is not processed by the z/OS Connect    *
  *                      server.                                 *
  ****************************************************************
  At runtime the z/OS Connect server incorrectly removed empty
  objects from JSON payloads. This caused remote endpoints to
  reject requests because required (but empty) objects were not
  present.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect has been changed to prevent the reported removal of
  empty objects during processing.
  
  API provider Gradle plug-in projects should be rebuilt with
  version 1.4.9 (or later).
  API requester Gradle plug-in projects should be rebuilt with
  version 1.2.3 (or later).
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect EE V3.0.91.0 (PH65316).
