June 2025 Summary for ministryofjustice/hmpps-assess-risks-and-needs-oastub-ui: Reliability improvements focused on error handling for existing associations. Implemented robust 409 Conflict error handling by checking both e.status and e.responseStatus, enabling graceful fallback in development and testing environments. The change reduces blockers in UI workflows when associations already exist and accelerates iteration with backend services. Commit 0a09babc88c9a4d1291cc65493a853849caace05 documents the fix (Fix 409 Conflict error in Dev and Test, #108). Business impact: fewer flaky errors, smoother dev/testing cycles, and improved user experience when creating or re-associating entities. Skills demonstrated include frontend error handling, HTTP status management, defensive coding, and Git-based traceability.
