Unauthorized

Sign with the key or origin that owns the target object, then retry

In System, the code passed to apply_authorized_upgrade does not hash to the value in AuthorizedUpgrade. In LimitOrders, the caller is not the order's signer, who alone may cancel it. Check the code hash against the authorization, or the sender against the order's signer.

Declared by the System, LimitOrders pallets; it classifies to the semantic code not_authorized.

Remediation

The same explanation is available in the terminal: btcli explain Unauthorized.
