Errors/Chain errors
HotKeyAccountNotExists
Register the hotkey on this subnet first with `btcli subnets register`
The hotkey has no on-chain account, meaning it was never created through registration, so staking or delegation operations cannot reference it. Check the Owner storage for the hotkey or btcli wallet overview; register the hotkey on a subnet first.
Declared by the SubtensorModule pallet; it classifies to the semantic code not_registered.
Remediation

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