HotKeyAlreadyRegisteredInSubNet

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

A registration or hotkey swap targeted a hotkey that already holds a UID on the subnet (or, for a swap without a netuid, on any subnet). Check the Uids storage for the (netuid, hotkey) pair or btcli wallet overview; use a different hotkey or netuid.

Declared by the SubtensorModule pallet; it classifies to the semantic code already_exists.

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