@ilblackdragon this is a known limitation. Registrar account id needs to be fetched from RPC (protocol config), and given how rarely this is needed, I decided that registrar operator can use a lower level transaction construction command instead of adding extra RPC call for all regular users using this command.

Thinking about it now, I wonder if we should just hardcode the registrar account id or make it configurable in the config file, so we don’t need to make that extra RPC call and yet registrar can still use this this command
