我正在尝试部分更新已经在索引中并且索引良好的现有文档，这意味着我可以在使用 timestamp 显示文档的字段。我只想更新医生的身份证 test_id 我的要求是：

POST shirkan_test/_update/test_id
{
  "doc": {
    "name": "shirkan"
  },
  "doc_as_upsert": true
}

获取以下错误：

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "failed to parse field [timestamp] of type [date] in document with id 'test_id'. Preview of field's value: '1.602505857664299E9'"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "failed to parse field [timestamp] of type [date] in document with id 'test_id'. Preview of field's value: '1.602505857664299E9'",
    "caused_by": {
      "type": "illegal_argument_exception",
      "reason": "failed to parse date field [1.602505857664299E9] with format [epoch_second]",
      "caused_by": {
        "type": "date_time_parse_exception",
        "reason": "Failed to parse with all enclosed parsers"
      }
    }
  },
  "status": 400
}

非常感谢您的帮助。谢谢。
编辑：添加索引Map

{
  "mapping": {
    "properties": {
      "condition": {
        "type": "text",
        "index": false
      },
      "name": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword",
            "ignore_above": 256
          }
        }
      },
      "rank": {
        "type": "double"
      },
      "timestamp": {
        "type": "date",
        "format": "epoch_second"
      }
    }
  }
}

编辑2:更改 timestamp 格式化为 strict_date_optional_time_nanos 不会产生这样的错误，而且upsert工作得很好。
