Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS Connect V3.0               *
  *                 apiRequester-1.0 feature for OpenAPI 2       *
  *                 API requesters, with locally generated JWTs. *

  * PROBLEM DESCRIPTION: Message "BAQR1143E: Internal server     *
  *                      error" is reported for API requesters,  *
  *                      due to a NullPointerException.          *
  ****************************************************************
  A z/OS Connect server was configured so that an API requester
  required a locally generated JWT but ran under an
  unauthenticated link user ID. Running this API requester under
  the default unauthenticated user ID resulted in the
  getCallerSubject() method call returning null.
  Null is a valid response on the getCallerSubject() method call
  and it should be handled appropriately and a
  NullPointerException should not be thrown.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect has been changed to report the following message
  when the getCallerSubject() method call returns null in the
  reported scenario:
  
  BAQR1408E: The SAF unauthenticated user ID <user ID> is not
             defined correctly or does not have READ access to the
             SURROGAT profile <profile_name>.
  
  The fix for this APAR is expected to be delivered by the PTFs
  for z/OS Connect V3.0.97.0 (PH67751).
