# InvalidAuthorizationMode (/docs/errors/chain/InvalidAuthorizationMode)

The order terms and authorization scheme do not match. Classical signatures require original V1 or V2 terms; account approval requires Authorized terms containing the owner-local nonce. Prepare and authorize the complete order again.

Declared by the `LimitOrders` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).

Declared at [`pallets/limit-orders/src/lib.rs#L550`](/code/pallets/limit-orders/src/lib.rs#L550).

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