# Named (/docs/errors/chain/Named)

An unnamed scheduler function was used on a task that was scheduled with a name. Use the named variants (`cancel_named`, `schedule_named`) with the task's id, which you can find via the `Lookup` storage map.

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