# AlreadyNoted (/docs/errors/chain/AlreadyNoted)

The preimage for this hash has already been noted on-chain, so `note_preimage` has nothing to add. Check `RequestStatusFor` (or legacy `StatusFor`) for the hash before submitting the bytes again.

Declared by the `Preimage` pallet; it classifies to the semantic code [`already_exists`](/docs/errors/already-exists).

## Remediation [#remediation]

The object or state already exists; treat the goal as met or pick a different target

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