# S01: Fix API Bugs — Review Detail 422 + Creators Page

**Goal:** Fix the 422 API error on review moment detail and creators browse page
**Demo:** After this: Review detail page and creators page load without errors using real pipeline data

## Tasks
- [x] **T01: Fixed 422 on review detail (added single-moment endpoint) and creators page (paginated response wrapper)** — 1. Reproduce the 422 on review moment detail — likely a schema mismatch with real data (null fields the Pydantic model doesn't expect)
2. Check the creators browse endpoint for the error
3. Fix schemas to handle nullable fields from real pipeline data
4. Test both endpoints with real data on ub01
