The return JSON is missing the array of rules, contrary to what is documented and what is done for directives/groups.
It is also displaying ruleCategories in place of rule:

Actual:

{
  "action": "createRule",
  "id": "e12b9720-66c0-4887-8026-f72cdc423a69",
  "result": "success",
  "data": {
    "ruleCategories": {
      "id": "e12b9720-66c0-4887-8026-f72cdc423a69",
      "displayName": "RTF generated rule",
      "shortDescription": "",
      "longDescription": "",
      "directives": [
        "b078d18e-7a99-4bd5-8386-43eaf4f3669f" 
      ],
      "targets": [
        "policyServer:root" 
      ],
      "enabled": true,
      "system": false,
      "tags": []
    }
  }
}

VS (should):

{
  "action": "createRule",
  "id": "e12b9720-66c0-4887-8026-f72cdc423a69",
  "result": "success",
  "data": {
    "rules": [ {
      "id": "e12b9720-66c0-4887-8026-f72cdc423a69",
      "displayName": "RTF generated rule",
      "shortDescription": "",
      "longDescription": "",
      "directives": [
        "b078d18e-7a99-4bd5-8386-43eaf4f3669f" 
      ],
      "targets": [
        "policyServer:root" 
      ],
      "enabled": true,
      "system": false,
      "tags": []
    }
    ]
  }
}
