I'm attempting to follow this tutorial  
[https://www.elastic.co/guide/en/elasticsearch/reference/7.x/getting-started-index-lifecycle-management.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/getting-started-index-lifecycle-management.html)  
And I am at the point where it says to Create an index template

```auto
PUT _index_template/timeseries_template
{
  "index_patterns": ["timeseries"],                   
  "data_stream": { },
  "template": {
    "settings": {
      "number_of_shards": 1,
      "number_of_replicas": 1,
      "index.lifecycle.name": "timeseries_policy"     
    }
  }
}

```

But I get this error

```auto
{
  "error" : {
    "root_cause" : [
      {
        "type" : "x_content_parse_exception",
        "reason" : "[3:3] [index_template] unknown field [data_stream]"
      }
    ],
    "type" : "x_content_parse_exception",
    "reason" : "[3:3] [index_template] unknown field [data_stream]"
  },
  "status" : 400
}

```

It also says you can use the `Kibana Create template wizard` but haven't found that yet in Kibana.

FYI 7.X is the master version of the docs, and can contain things that haven't been released yet. You should use [https://www.elastic.co/guide/en/elasticsearch/reference/current/getting-started-index-lifecycle-management.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/getting-started-index-lifecycle-management.html), or replace `current` for whatever version you are using.

What version are you running at the moment?
