# RelayerRequiredForPartialFill (/docs/errors/chain/RelayerRequiredForPartialFill)

A `partial_fill` was requested for an order whose `relayer` field is empty; partial fills are only permitted on orders that restrict who may execute them. Check the order payload and either set a relayer list or execute the full amount.

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