script 2：

PUT test_index_1
{

  "createTime": "2021-08-01 00:30:15",
  "modifiedTime": "2021-08-01 00:30:15.245",
  "finishTime": "2021-08-01 00:30:15.245666",
  "orderTime": 1593306078000,
  "extraInfo": {
    "name": "Bob",
    "age": 12,
    "isMale": true
  },
  "rate": 12.4321344612,
  "orderAmount": 432145,
  "txnFee": 1234.43,
  "merchantName": null,
  "txnStatus": 1
}

error message 1：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "parse_exception",
        "reason" : "unknown key [modifiedTime] for create index"
      }
    ],
    "type" : "parse_exception",
    "reason" : "unknown key [modifiedTime] for create index"
  },
  "status" : 400
}

error message 2：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Epoch [epoch_millis] is not supported as dynamic date format"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: Epoch [epoch_millis] is not supported as dynamic date format",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Epoch [epoch_millis] is not supported as dynamic date format"
    }
  },
  "status" : 400
}

question:

• How can I adjust the Dynamic Template (script 1) to ensure that the data in the script 2 can be written properly?
• If I add epoch_millis to the dynamic_date_formats, it will respond error message 2.
