Getting ElasticsearchStatusException and ElasticsearchResponseException?

What is ElasticsearchStatusException and ElasticsearchResponseException?

Caused by: org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=illegal_argument_exception, reason=request [/user_context/_refresh] contains unrecognized parameter: [ignore_throttled]] Caused by: org.elasticsearch.client.ResponseException: method [POST], host [ URI [/user_context/_refresh?ignore_throttled=false&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true], status line [HTTP/1.1 400 Bad Request] 

This is what I am getting, when trying to run my JavaSpring Code,

ERROR 26299 --- [ main] .d.e.r.s.AbstractElasticsearchRepository : failed to load elasticsearch nodes : ElasticsearchStatusException[method [HEAD], host [************] ............... 

ElasticSearch Version in pom.xml : 6.8.1 with Spring Data Elasticsearch version : 3.2.6

ElasticSearch Version of the Remote Server : 6.2.2

I am using High Level Rest Client.

 @Override @Bean public RestHighLevelClient elasticsearchClient() { final ClientConfiguration clientConfiguration = ClientConfiguration.builder() .connectedTo(elasticsearch_host + ":" + elasticsearch_port).build(); return RestClients.create(clientConfiguration).rest(); } 

Spring Version : 2.2.4
