Worked on the microsoft/graphrag repository to enhance the reliability of streaming output by addressing a configuration issue in the embedding store initialization. Using Python and API development skills, delivered a targeted bug fix that resolved a query error in streaming mode by renaming a misconfigured argument from conf_args to config_args. This change ensured correct configuration propagation throughout the streaming pipeline, reducing runtime errors and support incidents. The patch was implemented with a focus on maintainability and minimal risk, reinforcing robust streaming capabilities and clear configuration semantics. Demonstrated strong debugging and code review practices to stabilize the streaming path for future development.
