# F-097 — Implementer evidence

- Fixed the admin catch-all POST proxy: it no longer sends `Content-Type: application/json` when the request has no body.
- This allows `POST /api/products/:id/generate-seo` to reach the backend; previously Fastify rejected the empty request with `FST_ERR_CTP_EMPTY_JSON_BODY` (400).
- Rebuilt and restarted the production monolith.

Validation:
- Admin production build: exit 0
- Authenticated `/api/admin/settings`: HTTP 200
- Authenticated empty-body SEO request: HTTP 422 `AI_NOT_CONFIGURED` with actionable message (instead of HTTP 400)
