Smartlock state object missing in response

I’m trying to call the /smartlock GET endpoint. It succeeds, but the response body doesn’t contain the state object suggested by documentation. Do you guys have any suggestions on why that could be?

Call:
curl -X GET --header 'Accept: application/json' --header 'Authorization: Bearer <redacted> 'https://api.nuki.io/smartlock/<redacted>

Response:

{
  "smartlockId": <redacted>,
  "accountId": <redacted>,
  "type": 4,
  "authId": <redacted>,
  "name": <redacted>,
  "favorite": false,
  "serverState": 0,
  "adminPinState": 0,
  "virtualDevice": false,

    "creationDate": "2023-09-26T07:04:27.989Z"
  }
}
