Unavailable personal feature

Failed: rpc error: code = Unavailable desc = Unavailable personal feature

This means that on the node you connected to, personal account features are disabled using the setting personal = False. This setting is usually used on public nodes, so you cannot use personal account features when connecting to public nodes. Always create and use accounts using local nodes or offline, e.g. by generating private keys using one of Aergo’s SDKs. See also: Creating Accounts
