# NothingAuthorized (/docs/errors/chain/NothingAuthorized)

No code upgrade has been authorized, so `apply_authorized_upgrade` has nothing to apply. Check the `AuthorizedUpgrade` storage item in System; an authorization must be recorded before applying the new code.

Declared by the `System` pallet; it classifies to the semantic code [`not_found`](/docs/errors/not-found).
