The gateway appears to be stripping or failing to forward authentication headers entirely:
* Stored Keys: Requests using
cf-aig-authorization
cf-aig-authorization
fail with 401. * Manual Keys: Requests with an explicit
Authorization: Bearer
Authorization: Bearer
header also fail with the provider returning "No auth header provided". * Verified Keys: All API keys have been confirmed to work correctly when sent directly to providers, bypassing the AI Gateway. * Widespread Issue: This behavior persists even in the Cloudflare internal AI Search Playground.
