looks like SwitchboardP2PTransport isn't implementing __on_message_undelivered(command)
so the base class SwitchboardClient tries to call _on_error
but SwitchboardP2PTransport hasn't overridden _on_error, so SwitchboardClient raises a NotImplementedError
So Switchboard needs to implement _on_error, but I'm not sure what the implementation should look like.
