E2004#

A route middleware was referenced (usually via definePageMeta({ middleware: [...] })) but no middleware with that name exists. Common causes are a typo in the name, or a middleware file that was renamed or deleted without updating its references.

Resolution#

Make sure the name matches a file in middleware/. Names are derived from the filename: middleware/auth.ts is referenced as auth.
