Subject: [PATCH 2/2] Fix Jackson 2.20 API compatibility issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated deprecated Jackson API usage to work with 2.20:
- Replaced mappingException() calls with reportInputMismatch() and handleUnexpectedToken()
- Updated setSerializationInclusion() to setDefaultPropertyInclusion()
- Removed deprecated WRITE_NULL_MAP_VALUES configuration
