Worked on the zeek/zeek repository to enhance error handling and testing reliability for JSON parsing workflows. Focused on improving the from_json function so that error details are returned programmatically, rather than printed to stdout, enabling better downstream integration and automated error capture. Updated test baselines in the zam module to align expected outputs with actual system behavior, reducing false positives and improving CI stability. Utilized Zeek scripting and JSON parsing skills to clarify error propagation and maintain traceability in test changes. The work emphasized baseline management and robust testing practices, supporting maintainers and future improvements in error-driven workflows.
