versionone发布创建任务失败

Question

使用带有Python请求的json创建任务，失败并显示：

{ "_type": "Error", "error": "Bad Request", "exceptions": [ { "type": "DataException", "message": "Violation'NotSupported" } ] }

使用的网址：SetThreadPriority

以下是请求的正文：（标头是通常的；授权，内容类型，接受）

    },
    "Name": {
      "value": "Scrum Meetings/Team Mgmt",
      "act": "set"

  }
}

有关此请求出了什么问题的任何想法？ （发现这种操作的例子很少）
