Dynamic mapping strict and date data type (ES 6.4)

Elastic Stack Elasticsearch
1

I have created an index with following mapping:

{
  "mappings": {
    "_doc": {
      "dynamic": "strict",
      "properties": {
        "created ": {
          "type": "date",
          "format": "yyyy/MM/dd HH:mm:ss||yyyy/MM/dd"
        }
      }
    }
  }
}

Then I try index a new document as:

PUT test1/_doc/1
{
  "created": "2016/01/01"
}

This is resulting in the following error:

{
  "error": {
    "root_cause": [
      {
        "type": "strict_dynamic_mapping_exception",
        "reason": "mapping set to strict, dynamic introduction of [created] within [_doc] is not allowed"
      }
    ],
    "type": "strict_dynamic_mapping_exception",
    "reason": "mapping set to strict, dynamic introduction of [created] within [_doc] is not allowed"
  },
  "status": 400
}

When I change "dynamic": "strict" to "dynamic": false then even though the document get indexed but the field doesn't behave like a date field. The range query doesn't work. If I completely remove the dynamic param from mapping then everything works as expected but the requirement is to keep dynamic as strict.

Please explain me why such a behaviour and how it can be solved.

The field name in your mapping has a trailing space.

Thanks a lot. Sometimes it just a silly mistake.
