Worked on enhancing the TeamInfoCall functionality in the BerriAI/litellm repository by implementing URL-encoding for the team_id parameter, ensuring that spaces and special characters are safely handled during API integration. This update prevents API errors and improves data integrity when performing team lookups. The approach included adding comprehensive tests to verify correct encoding behavior and to confirm that no team_id is appended when the value is null, guarding against regressions and edge-case failures. Utilized TypeScript for both front end development and testing, focusing on reliability and correctness in handling user input and API requests within the codebase.
