Worked on the GetStream/stream-node repository to enhance the Feeds API by enforcing the presence of a user_id when updating comments. This feature, developed using TypeScript and focused on backend and API development, ensures that every comment update is explicitly attributed to a specific user. By making user_id mandatory, the update improved data integrity and enabled more reliable traceability for audit and governance purposes. The implementation aligned with the FEEDS-819 requirement, introducing minimal risk to existing API consumers while laying the groundwork for future improvements in debugging and compliance. No bug fixes were recorded during this period.
