When I am trying to create a template I am getting an error. I am using this as a reference: **"[https://www.elastic.co/guide/en/elasticsearch/reference/6.7/indices-templates.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.7/indices-templates.html)"**

Perhaps if you share the error we can assist in resolving it.
