PH66635: LEGACY PR DIFF API RETURNS ITS RESPONSE AS A PLAIN STRING, WHICH HAS A 16K LIMIT CAUSING ISSUES WHEN RESPONSE EXCEEDS THRESHOLD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The legacy PR Diff API returns its response as a plain String,
  which imposes a 16 KB size limit. This limitation causes issues
  when the response exceeds the threshold.
  
  When the API returns large Diff DDL content exceeding 16 KB, it
  results in a 500 Internal Server Error, which in turn causes
  failures in the UI. To resolve this, we introduced a new version
  of the API (on the same endpoint) that returns the response in
  JSON format, allowing support for larger payloads.
  
  
  Affected Users: DevOps administrators and users working on the
  pull request workflow in DevOps Experience.
  you need Prerequisite UMS 1.2.0.10 in order for this fix to be
  applied.
