40102 — invalid_api_key

X-Fluxy-Api-Key is missing, revoked, or not an fc_ server key. pk_ keys cannot mint member JWTs.

At a glance — HTTP 401 · terminal for that request.

What to do

• Send the project's fc_ key on the server-side call that needs it (POST /auth/token, admin routes, REST) — see the Auth / JWT cookbook.
• pk_ publishable keys are for public rooms in the browser. They never mint JWTs.
• If the key was rotated, update the server environment and retry.
