I'm attempting to update groups for a host via the API using the host.update method. I would expect that the only parameters I would have to give are what is being changed. However, the API errors, insisting that I also send it the tls_psk_identity (and tls_psk as well if I only add tls_psk_identity). Node is configured to use encryption and everything else is working correctly. I can work around the issue by submitting the same encryption info I did when I set up the node.

 {
  "code": -32602,
  "message": "Invalid params.",
  "data": "Incorrect value for field \"tls_psk_identity\": cannot be empty."
}

on request:
