I am new to elastic search, I was going through this video : [https://www.elastic.co/webinars/getting-started-elasticsearch](https://www.elastic.co/webinars/getting-started-elasticsearch).

Installed elasticsearch-5.5.0 (linux 64 bit) and kibana 5.5.0 and xpack.

When I create the index using the following command, I am getting an error.

```
PUT /dates
{
  "settings": {
    "index": {
      "number_of_shards": 2,
      "number_of_replicas": 0
    },
    "mappings": {
      "birth-date": {
        "properties": {
          "dob": {
            "type": "date",
            "format": "year_month_day"
          }
        }
      }
    }
  }
}

```

ERROR:

```
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "unknown setting [index.mappings.birth-date.properties.dob.format] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "unknown setting [index.mappings.birth-date.properties.dob.format] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"
  },
  "status": 400
}

```

As mentioned in the response I tried searching in breaking changes, but unable to find the reason anywhere.

I think your closing curly braces are misaligned. The key `mappings` should be at the same nesting as `settings`.

Thanks. This was the issue.  
I have updated the examples as per webinar in this gitlab example repo: [https://github.com/jayakrishnankk/examples/tree/master/getting-started](https://github.com/jayakrishnankk/examples/tree/master/getting-started) which is a clone of [https://github.com/elastic/examples](https://github.com/elastic/examples)
