I am getting error when giving multiple term aggregation in composite aggregation sources

[es/search] failed: [x_content_parse_exception] [1:177] [composite] failed to parse field [sources]

my code as below

            Map<String, CompositeAggregationSource> map = new HashMap<>();

            map.put("Term1",
                    new CompositeAggregationSource.Builder().terms(d->d
                            .order(NamedValue.of("_key",SortOrder.Asc))
                            .field("agent.name")
                    ).build()
            );
            
            map.put("Term2",
                    new CompositeAggregationSource.Builder().terms(d->d
                            .order(NamedValue.of("_key",SortOrder.Asc))
                            .field("agent.type")
                    ).build()
            );
            
            List<Map<String, CompositeAggregationSource>> list = new ArrayList<>();
            list.add(map);

            SearchResponse<Void> response = client.search(b -> b
                            .index("*winlogbeat*")
                            .size(0)
                            .aggregations("name", t->t
                                    .composite(t1->t1
                                            .sources(map)))
                    ,
                    Void.class
            );
