I am trying to encrypt HTTP client communications as the doc in  
[https://www.elastic.co/guide/en/elasticsearch/reference/7.x/configuring-tls.html#tls-http](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/configuring-tls.html#tls-http). But when I execute this command it prompts an error as follows.  
`ERROR: Unknown command [http]`  
Is there something I missed here?
