date - 格式错误的日期字段填充到弹性搜索中的新字段

Question

我在 elasticsearch 中创建了一个具有多个日期字段的索引，并将列格式化为yyyy-mm-dd HH:mm:ss. 最终我发现日期格式不正确，并且在字段中填充了错误的数据。该索引有超过 600 000 条记录，我不想留下任何数据。现在我需要创建另一个字段或具有相同日期字段和格式的新索引，YYYY-MM-ddTHH:mm:ss.Z并且需要将所有记录填充到新索引或新字段中。

我使用了如下的日期处理器管道。但它失败了。在这里纠正我的任何错误。

PUT _ingest/pipeline/date-malform
{
  "description": "convert malformed date to timestamp",
    "processors": [      
      {
        "date": {
          "field": "event_tm",
          "target_field" : "event_tm",
          "formats" : ["YYYY-MM-ddThh:mm:ss.Z"]
          "timezone" : "UTC"
        }
      },      
      {
        "date": {
          "field": "vendor_start_dt",
          "target_field" : "vendor_start_dt",
          "formats" : ["YYYY-MM-ddThh:mm:ss.Z"]
          "timezone" : "UTC"
        }
      },
        {
        "date": {
          "field": "vendor_end_dt",
          "target_field" : "vendor_end_dt",
          "formats" : ["YYYY-MM-ddThh:mm:ss.Z"]
          "timezone" : "UTC"
        }
      }   
    ]
}

我已经创建了管道并使用了重新索引，如下所示

POST _reindex
{
  "source": {
    "index": "tog_gen_test"
  },
  "dest": {
    "index": "data_mv",
    "pipeline": "some_ingest_pipeline",
    "version_type": "external"
  }
}

运行重新索引时出现以下错误

    {
      "index": "data_mv",
      "type": "_doc",
      "id": "rwN64WgB936y_JOyjc57",
      "cause": {

            }
          }
