Summary
Fixes #2106.
Root cause:
matchAPIRouteused the full pathname (e.g./admin/api/my-route) while routes are registered without the base prefix (e.g./api/my-route). Whenserver.baseURLis configured, the base prefix was not stripped before lookup, causing all API routes to return 404.Fix: Strip the
baseURLprefix from the pathname before matching API routes.Changes
