A similar calll (troncated from the first level keys of the response) in 8.1 will return something like this:

{
  "nodes": [
    {
      "id": "9df180c9-0cea-4ccc-ba3b-b1931e433e3c",
      "status": "accepted",
      "hostname": "DeployDirectiveAgent1.rudder.local",
      "osName": "Debian",
      "osVersion": "[11]",
      "machineType": "Virtual" 
    }
  ]
