Worked on improving the reliability of template rendering in the infiniflow/ragflow repository, focusing on a critical bug that affected string formatting by incorrectly removing all quotation marks from rendered outputs. Addressed this issue by implementing selective JSON serialization within the Template component and eliminating global quote stripping, ensuring that essential quotes are preserved during template substitutions. Utilized Python and backend development skills, with particular attention to robust JSON handling. This targeted fix enhanced the integrity and maintainability of the rendering pipeline, reducing the risk of misformatted content and laying a more stable foundation for future feature development and support.
