type date is been covert to text in elasticsearch (v5.4.0)

Question

The type of field version in following mapping is date. But the type of version listed on groups/_mapping is text. Is there anything wrong about the mapping or settings ? Thanks.

mapping:

PUT groups

{
  "settings": {
    "index.mapping.ignore_malformed": true
  },
  "mappings": {
     "shop": {
      "_all":  { "enabled": false  },
      "dynamic": "false",
      "date_detection" : false,
      "properties": {
          "sid":      { "type": "keyword"},
          "version":  {
              "type":   "date",
              "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
          }
      }
    }
  }
}

the result for this is.

{
    "acknowledged": true,
    "shards_acknowledged": true
}

result from http://host:9200/groups/_mapping

{
  "groups": {
    "mappings": {
      "shop": {
        "properties": {
          "sid": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "version": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          }
        }
      }
    }
  }
}

Insert data as follow:

{'sid': '772634b9b9a8437f9cbfaec2b546f8af', 'version': '20131209 15:19:04'}

The response:

{
    '_id': '772634b9b9a8437f9cbfaec2b546f8af',
    '_index': 'groups_version',
    '_shards': {'failed': 0, 'successful': 2, 'total': 2},
    '_type': 'shop',
    '_version': 1,
    'result': 'created',
}

I think I might know what is going on - in Kibana when you put an empty line between PUT group and the body {} it does not append the body to the reguest and the only request that is sent is:

curl -XPUT "http://localhost:9200/groups"

That is why you got standard mapping with text. But if you remove the empty line everythnig is fine and this request is sent:

curl -XPUT "http://localhost:9200/groups" -H 'Content-Type: application/json' -d'
{ "body": {
  "settings": {
    "index.mapping.ignore_malformed": true
  },
  "mappings": {
     "shop": {
      "_all":  { "enabled": false  },
      "dynamic": "false",
      "date_detection" : false,
      "properties": {
          "sid":      { "type": "keyword"},
          "version":  {
              "type":   "date",
              "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
          }
      }
    }
  }
}
}'

It is easy to check what is really sent when you click the "wrench" button, then "Copy as cURL" and paste it somewhere:
