我最近刚刚将集群从6.1.x升级到7.9.x版本。尝试修复索引模板，以便在午夜过后推送数据时，自动创建新的每日索引。
我是这样做的：

## create template and mapping

PUT http://es1:9200/_template/tmp_staging_devices_1
{
    "template": "staging-devices-*",
    "settings": {
        "number_of_shards": 3
    },
    "mappings": {
        "properties": {
            "ts": {"type": "date", "format": "epoch_millis"},
            "server_ts": {"type": "date", "format": "epoch_millis"},
            "raw": {"type": "binary"}
        }
    }
}

## template is listed under the list of templates

## trying to put some data into the elasticsearch

PUT http://es1:9200/staging-devices-2020-10-20
{
    "imei": "24779610124313",
    "json": "{\"imei\":\"357796101614313\",\"ts\":1603180834000,\"values\":{\"coreMsgId\":2810,\"obdIt\":{\"distance\":0,\"distanceCombustion\":0,\"idleTime\":0,\"idleTimeCombustion\":0,\"maxSpeed\":0,\"totalEnergyCons\":0,\"totalFuelCons\":0,\"totalTime\":488,\"totalTimeCombustion\":0}}}",
    "raw": "04 00 00 32 0A 18 08 FA 15 32 13 08 00 10 00 18 00 20 00 28 E8 03 30 00 38 00 40 00 48 00 12 0F 33 35 37 37 39 36 31 30 31 36 31 34 33 31 33 18 C2 EE CE D1 CB 2E",
    "server_ts": 1603180834000,
    "ts": 1603180834000
}

## error that I get back (400 bad request)

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

我做错什么了？
与“旧系统”唯一不同的是我删除了“值”

{
    "template": "staging-devices*",
    "settings": {
        "number_of_shards": 1
    },
    "mappings": {
        "values": {
            "properties": {
                "ts": {"type": "date", "format": "epoch_millis"},
                "server_ts": {"type": "date", "format": "epoch_millis"},
                "raw": {"type": "binary"}
            }
        }
    }
}
