  ****************************************************************
  The z/OS Connect OpenAPI 3 API requester did not correctly
  manage response data larger than 32KB returned by the z/OS
  Client Web Enablement Toolkit streaming callback service. This
  caused early termination when the API requester received
  multiple transmission responses.
  

Problem conclusion

Temporary fix

Comments

• The z/OS Connect API requester Host API callable interface has
  been changed to correctly handle response data returned in more
  than one chunk. This allows all the response data to be returned
  to z/OS application API requesters in multiple transmissions.
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect V3.0.82.0 (PH61452).
