使用LUIS Programmatic API导出模型时，预构建的实体不会映射到话语

Question

当我尝试导出具有预构建实体的LUIS模型时，预构建的实体不会在话语中注释。我得到以下JSON有效负载作为对Export Model API

的响应

{
  "luis_schema_version": "2.1.0",
  "versionId": "0.1",
  "name": "SampleApp",
  "desc": "",
  "culture": "en-us",
  "intents": [
    {
      "name": "None"
    },
    {
      "name": "testintent"
    }
  ],
  "entities": [],
  "composites": [],
  "closedLists": [],
  "bing_entities": [
    "age",
    "datetimeV2",
    "email",
    "number",
    "url"
  ],
  "model_features": [],
  "regex_features": [],
  "utterances": [
    {
      "text": "i want to go to beach tomorrow",
      "intent": "testintent",
      "entities": []
    },
    {
      "text": "my age is 22 years old",
      "intent": "testintent",
      "entities": []
    },
    {
      "text": "a is 5 % to less compared to b",
      "intent": "testintent",
      "entities": []
    }
  ]
}

这里以“ 我想明天去海滩 ”为例说明。我明天标记为DateTime.V2实体。但是在导出的模型中，与带注释的实体相比，DateTime.V2实体将作为空白JSON数组出现。

这是我带注释的话语视图

这是我的实体视图

以下是导出模型的GET请求： https://westus.api.cognitive.microsoft.com/luis/api/v2.0/apps/ced3182d-12bb-4961-a163-63dff5cdf47a/versions/0.1/export

有人可以告诉我原因吗？ 有没有办法以下列方式获取带注释的预建实体：

{
      "text": "i want to go to beach tomorrow",
      "intent": "testintent",
      "entities": [
                   {
                      "entity": "builtin.datetime.v2",
                      "startPos": 22,
                      "endPos":   29
                   }
                  ]
}
