It is documented here:
It is also listed in the quick start guide here:

Your deployment tool should be configuring that for you.

Exception: 'NoneType' object has no attribute 'encode'" log message shows that the health-manager receives the heartbeat packets from the amphorae but it is unable to decode them. Those packets are encrypted JSON messages and it seems that the key ([health_manager].heartbeat_key see https://docs.openstack.org/octavia/latest/configuration/configref.html#health-manager) used to encrypt those messages is not defined in your configuration file. So I would suggest configuring it and restarting the Octavia services, then you can re-create or failover the load balancers (you cannot change this parameter in a running load balancer).
