azure - 保存和重新训练的 QnA Maker KB 元数据限制

Question

所以我看到的问题是向知识库添加新的 QnA 对以及更新现有的对。当添加一个新的 QnA 对时，当添加超过 5 个元数据字段时，我会得到以下响应qnamaker/v4.0/operations/{kbId}：

对于此有效负载：

{
  "add": {
    "qnaList": [
      {
        "questions": [
          "What is the meaning of life"
        ],
        "answer": "To feel loved",
        "score": 0,
        "id": 0,
        "source": null,
        "metadata": [
          {

          {
            "name": "modifiedby",
            "value": "svb"
          },
          {

            "value": "Apr 17, 2021"
          },
          {
            "name": "__primaryquestionhash__",
            "value": "48aabdff996a9733464c0b2b5b05757e764729ac6441e0a9bc4881d6156f4d12"
          },
          {

            "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.",
        "score": 0,
        "id": 0,
        "source": null,
        "metadata": [
          {
            "name": "__listitemid__",
            "value": "2"
          },
          {
            "name": "modifiedby",
            "value": "svb"
          },
          {
            "name": "modifiedon",
            "value": "Apr 17, 2021"
          },
          {
            "name": "__primaryquestionhash__",
            "value": "9872d662195d4eb8218d25ef5da6bc8a216c68b771b4e9be5b1800bc354652b6"
          },
          {
            "name": "filter_dba87721dfbd4c16b563e7b6d932da65",
            "value": "%7b%22name%22%3a%22Category%22%2c%22value%22%3a%22Covers%22%7d"
          }
        ],
        "autoSelected": false,
        "sharePointListItemIdentifier": null
      }
    ]
  },
  "delete": {
    "ids": []
  },
  "update": {
    "name": null,
    "qnaList": []
  }
}

然而，这个带有 4 个元数据对的示例返回成功：

{
  "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"
          }
        ],
        "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.",
        "score": 0,
        "id": 0,
        "source": null,
        "metadata": [
          {
            "name": "__listitemid__",
            "value": "2"
          },
          {
            "name": "modifiedby",
            "value": "svb"
          },
          {
            "name": "modifiedon",
            "value": "Apr 17, 2021"
          },
          {
            "name": "__primaryquestionhash__",
            "value": "9872d662195d4eb8218d25ef5da6bc8a216c68b771b4e9be5b1800bc354652b6"
          }
        ],
        "autoSelected": false,
        "sharePointListItemIdentifier": null
      }
    ]
  },
  "delete": {
    "ids": []
  },
  "update": {
    "name": null,
    "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，我也会得到一个 operationStatus 的Failed返回 - 即使文档说：Maximum number of metadata fields added or deleted: 10- 我假设这意味着单个 QnA 对总共有 10 次更新和删除。

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？

供参考 - 我们正在使用 QnA Maker v4（在美国西部）。

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