QnA Maker KB 元数据对保存和重新训练的限制

如何解决QnA Maker KB 元数据对保存和重新训练的限制

所以我看到的问题是将新的 QnA 对添加到知识库以及更新现有的对。添加新的 QnA Pair 时，添加超过 5 个元数据字段时，我会从 qnamaker/v4.0/operations/{kbId} 得到以下响应：

对于这个有效载荷：

{
  "add": {
    "qnaList": [
      {
        "questions": [
          "What is the meaning of life"
        ],"answer": "To feel loved","score": 0,"id": 0,"source": null,"metadata": [
          {
            "name": "__listitemid__","value": "1"
          },{
            "name": "modifiedby","value": "svb"
          },{
            "name": "modifiedon","value": "Apr 17,2021"
          },{
            "name": "__primaryquestionhash__","value": "48aabdff996a9733464c0b2b5b05757e764729ac6441e0a9bc4881d6156f4d12"
          },{
            "name": "filter_da8981d9d060415e947771ee3d1c65dd","value": "%7b%22name%22%3a%22Category%22%2c%22value%22%3a%22Biography%22%7d"
          }
        ],"autoSelected": false,"sharePointListItemIdentifier": null
      },{
        "questions": [
          "I have no idea what this answer could be.","Who is the giver of life?"
        ],"answer": "This cannot be answered - it is all based on perception.","value": "2"
          },"value": "9872d662195d4eb8218d25ef5da6bc8a216c68b771b4e9be5b1800bc354652b6"
          },{
            "name": "filter_dba87721dfbd4c16b563e7b6d932da65","value": "%7b%22name%22%3a%22Category%22%2c%22value%22%3a%22Covers%22%7d"
          }
        ],"sharePointListItemIdentifier": null
      }
    ]
  },"delete": {
    "ids": []
  },"update": {
    "name": null,"qnaList": []
  }
}

这里有 4 个元数据对的这个例子成功了：

{
  "add": {
    "qnaList": [
      {
        "questions": [
          "What is the meaning of life"
        ],"value": "48aabdff996a9733464c0b2b5b05757e764729ac6441e0a9bc4881d6156f4d12"
          }
        ],"value": "9872d662195d4eb8218d25ef5da6bc8a216c68b771b4e9be5b1800bc354652b6"
          }
        ],"qnaList": []
  }
}

看这个，附加值不包含任何无效字符或超过字符限制。此外，如果我尝试通过更新添加更多元数据字段，我也会得到 Failed 的 operationStatus - 即使文档说：Maximum number of metadata fields added or deleted: 10 - 我假设这意味着 10 次更新和删除单个 QnA 对的总数。

我不确定我是否做错了什么，或者这是否是 QnA Maker 方面的问题？

仅供参考 - 我们使用的是 QnA Maker v4（在美国西部）。

以下是更新字段失败的更新负载示例：

{
  "add": {
    "qnaList": []
  },"update": {
    "name": "test-something-here","qnaList": [
      {
        "id": 1,"questions": {
          "add": [],"delete": []
        },"metadata": {
          "add": [
            {
              "name": "__listitemid__","value": "1"
            },{
              "name": "modifiedby","value": "Test User"
            },{
              "name": "modifiedon",2021"

            }
          ],"delete": [
            {
              "name": "__listitemid__","value": "test user"

            }
          ]
        }
      },{
        "id": 2,"value": "2"
            },"value": "9872d662195d4eb8218d25ef5da6bc8a216c68b771b4e9be5b1800bc354652b6"

            }
          ]
        }
      }
    ]
  }
}

*** 编辑： 我还注意到具有此名称 filter_da8981d9d060415e947771ee3d1c65dd 的元数据字段失败，但具有此名称 filter_17c0a557aacc4e48a36f798c4504500f 的元数据字段没有（包含相同的值字段） - 后台是否有一些奇怪的模糊失败？
