Worked on the opsmill/infrahub-sdk-python repository to enhance file handling resilience by improving the read_file utility’s error messaging. Focused on clarifying File Not Found exceptions by specifying the expected file location, which aids users in diagnosing missing files more efficiently. The update included a parameter rename from file_name to file_path, requiring careful refactoring of downstream function signatures and associated unit tests to maintain API consistency. Leveraged Python for both implementation and testing, emphasizing robust error handling and thorough unit test coverage. These changes improved code quality and reduced debugging time for downstream integrations, reflecting a methodical approach to API evolution.
