org.elasticsearch.ElasticsearchStatusException: Elasticsearch exception [type=illegal_argument_exception, reason=request [/_search] contains unrecognized parameter: [ccs_minimize_roundtrips]]

Im getting the same error eventhough i changed to 7.2.0 of my elastic search jar.
I saw some previous discussions, where they asked to set to null. Since this is boolean i cant set it to null. this is annoying.

My search request is

    SearchRequest searchRequest = new SearchRequest();
    searchRequest.source(searchSourceBuilder);
    RestHighLevelClient client=elasticsearchConfig.client();
    SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

Please help!!1

Can you make sure that you are sending your request to the proper Elasticsearch instance? I suspect it is on an older version that does not support yet ccs_minimize_roundtrips. Maybe you have a cluster on multiple versions?
