I have 2 POJOs (Person and Car) where one is referred by the other

@Document(indexName = "person", type = "user")
public class Person 

 @Id
 private String id;

 private String name;

 @Field(type = FieldType.Nested)
 private Car car;

//getter and setter

This is the Car object which is referred as a nested in the Person object

public class Car 

 private String name;

 private String model;

//getter and setter

This is my REST end point. Here I am trying to return the person who has the given car model. I am sending the car model as a path variable and I am creating a QueryBuilder object

@RequestMapping(value = "/api/carModel")
 public List<Map<String,Object>> search(@PathVariable final String carModel) 
 QueryBuilder queryBuilder = QueryBuilders.nestedQuery(
 "car",
 QueryBuilders.boolQuery().must(QueryBuilders.matchQuery("car.model", carModel)),
 ScoreMode.None);

 final SearchRequestBuilder searchRequestBuilder = client.prepareSearch("person")
 .setTypes("user")
 .setSearchType(SearchType.QUERY_THEN_FETCH)
 .setQuery(queryBuilder);

 final SearchResponse response = searchRequestBuilder.get();

 List<Map<String,Object>> resultList = new ArrayList<>();
 List<SearchHit> searchHits = Arrays.asList(response.getHits().getHits());
 for (SearchHit hit : searchHits) 
 resultList.add(hit.getSourceAsMap());
 

 return resultList;
 

There is an exception occurred at final SearchResponse response = searchRequestBuilder.get(); saying java.lang.IllegalStateException: [nested] failed to find nested object under path [car]
