Worked on enhancing the reliability of the Zotero connector within the HKUDS/CLI-Anything repository, focusing on backend development and API integration using Python. Addressed issues with HTTP 400 errors by setting a default Content-Type for raw data in connector requests, which enabled the handling of larger payloads and improved error handling. Increased connector timeouts to better support the import and update of larger datasets, resulting in a higher success rate for data synchronization tasks. The technical approach emphasized robust network programming practices, ultimately improving the scalability and resilience of data imports and updates without introducing new bugs during the development period.
