Worked on the Protofy-xyz/Protofy repository to enhance the stability and reliability of API integrations, focusing on error handling within TypeScript code. Addressed a critical bug in the chatgpt API call path by normalizing the 'files' input to always be an array, defaulting to an empty array when necessary, which prevented undefined runtime errors and reduced system outages. Emphasized defensive programming practices to improve input validation and ensure consistent data structures across API interactions. Documented edge-case handling to support maintainability and future development. The work prioritized robust automated workflows and contributed to the continuity of service without introducing new features.
