Missing required property 'Highlight.fields'

[Ali5 (Ali)]

i am using elasticsearch bool querry with springboot application my querry is as follow:

public  List<feed> search(String id) throws IOException {
       
           Query bodyTermQuery = TermQuery.of(tq -> tq.field("body").value(id))._toQuery();
           Query titleTermQuery = TermQuery.of(tq -> tq.field("title").value(id))._toQuery();

           Query matchQuery = MatchQuery.of(mq -> mq.field("comment.c_text").query(id))._toQuery();

           Query nestedQuery = NestedQuery.of(nq -> nq.path("comment").query(matchQuery)
                           .innerHits(ih -> ih.highlight(h -> h.requireFieldMatch(true))))._toQuery();

           SearchResponse<feed> searchResponse = elasticsearchClient.search(
                           s -> s.index("feeds").query(q -> q.bool(b -> b.should(nestedQuery, titleTermQuery, bodyTermQuery))),
                           feed.class);
         
           
           List<Hit<feed>> hits = searchResponse.hits().hits();
           List<feed> feeds = new ArrayList<>();
           feed f=null;
           for(Hit object : hits){
        	   f = (feed) object.source();
        	   System.out.println("Feed : "+ f.getComment().get(1).getC_text());
               feeds.add(f); }
           
           return feeds;    
           }

i dont why it is not working in my springboot application i have used kibana to get my desired output and working fine but in my springboot application it didnt give my out the querry i used on kibana is as follow :
