Worked on stabilizing the FsCat command in the lakeFS repository by addressing a critical bug related to HTTP error handling. Focused on backend development using Go, the work involved implementing robust error validation after HTTP responses in the fs_cat command-line interface. This approach ensured that unhandled errors were properly detected and propagated, reducing inconsistent failure modes and improving overall system reliability. The targeted fix enhanced error observability and minimized support incidents for end users. The change was isolated and low-risk, making it suitable for production deployment. Emphasis was placed on error handling and command line interface best practices throughout the process.
