versionone发布创建任务失败

如何解决versionone发布创建任务失败

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）

{
  "Attributes": {
    "Parent": {
      "value": {
        "href": "/INSTANCE/rest-1.v1/Data/Story/1520179","idref": "Story:1520179"
      },"act": "set"
    },"Category": {
      "value": {
        "href": "/INSTANCE/rest-1.v1/Data/TaskCategory/113","idref": "TaskCategory:113"
      },"Source": {
      "value": {
        "href": "/INSTANCE/rest-1.v1/Data/TaskSource/954121","idref": "TaskSource:954121"
      },"Status": {
      "value": {
        "href": "/INSTANCE/rest-1.v1/Data/TaskStatus/123","idref": "TaskStatus:123"
      },"Owners": {
      "value": {
        "href": "/INSTANCE/rest-1.v1/Data/Member/1337179","idref": "Member:1337179"
      },"act": "add"
    },"Order": {
      "value": "1073828387","Todo": {
      "value": 6,"DetailEstimate": {
      "value": 6,"Description": {

}

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）
