ElasticSearch Suggestion not working

Elastic Stack Elasticsearch
1

Hi,

I am trying to add ElasticSearch Suggestion in my response and implementing it using SearchRequestBuilder as:-
SearchResponse searchResponse = searchRequestBuilder.execute().actionGet(1m);

Query is correct as I tried it using kibana but Java API is showing me below error:

I debugged this and found that registry content for suggestion from elasticsearch-httpclient-7.2.1.jar -> org.codelibs.elasticsearch.client.HttpClient -> getDefaultNamedXContents() is commented.

    //        entries.add(new NamedXContentRegistry.Entry(Suggest.Suggestion.class, new ParseField(TermSuggestion.NAME),
    //                (parser, context) -> TermSuggestion.fromXContent(parser, (String) context)));
    //        entries.add(new NamedXContentRegistry.Entry(Suggest.Suggestion.class, new ParseField(PhraseSuggestion.NAME),
    //                (parser, context) -> PhraseSuggestion.fromXContent(parser, (String) context)));
    //        entries.add(new NamedXContentRegistry.Entry(Suggest.Suggestion.class, new ParseField(CompletionSuggestion.NAME),
    //                (parser, context) -> CompletionSuggestion.fromXContent(parser, (String) context)));

Why is that part commented? Is their any other jar I'll have to use? Can someone please help me with this?

Thanks,
Shweta
