Feb 1, 2025February 2025: Delivered two core feature areas for GSA/datagov-harvester that advance data quality visibility and API reliability. Harvest Job Error Reporting UI Improvements and Data Export modernized error data retrieval/display, UI, and asset management with tests/docs updates. API Authentication and Response Consistency Improvements strengthened authorization checks and standardized HTTP status codes across Flask endpoints, with added tests and lint fixes. These changes, along with static asset migration (CSS/SCSS) and USWDS styling, reduce troubleshooting time, improve data export reliability, and promote consistent, secure API behavior.
