`timestamp` 字段对于 "Date Histogram" 聚合无效

Question

由于

，Kibana 7.x 中的查看索引出现问题

Error: Saved field "value.request.timestamp" of index pattern "flight-cache-*" is invalid for use with the "Date Histogram" aggregation. Please select a new field.

文档 json 看起来像（删除了不相关的属性）：

{
  "value": {
    "request": {
        "timestamp": 1638345701217
    }
  }
}

索引映射看起来像（也经过简化）

{
  "properties": {
    "value": {
       {
          "request": {
            "type": "nested",
            "properties": {
              "timestamp": {
                "format": "epoch_millis",
                "type": "date"
              }
            }
         }
      }
    }
  }
}

请帮忙。谢谢！

事实证明，Kibana 不支持在嵌套属性下使用时间戳。

将 request.type 更改为 object 解决了问题。
