Fix Failing Integration Endpoints

Start the "Fix Failing Integration Endpoints" loop.

Goal: Restore full functionality to all integration API endpoints
Max iterations: 10
Between iterations run: npm run test:integration
Exit when: All integration tests pass successfully


Start by executing 'npm run test:integration' to identify failing API endpoints. For each failing test, analyze the error message and relevant API code to determine the cause. Apply minimal, focused fixes to resolve the issue, then re-run the tests. Continue this process until all integration tests pass or you've reached 10 iterations.

Self-pace this loop. After each iteration, run `npm run test:integration` and evaluate the output, and only continue if the exit condition is not met (All integration tests pass successfully). Stop when the exit condition passes or 10 iterations are reached. Give a short status update each pass.
