Worked on the infiniflow/ragflow repository to enhance the reliability of session management within the agent OpenAI completion flow. Focused on backend and API development using Python, the work addressed a bug where session identifiers could be duplicated or misrouted, potentially impacting data integrity and completion routing. The solution involved clarifying and hardening the logic for selecting the correct session_id, ensuring that only the appropriate identifier is passed through each flow. This targeted fix improved the stability of OpenAI-based completions without affecting existing functionality, resulting in more robust handling of session data and a smoother end-user experience.
