Spring Data Couchbase / Spring Boot: could not get nested list of an object

I am new to couchbase and I am encountering an issue on fetching document from couchbase. The nested list of object (List of Devices) is always null. I used Spring Boot and Spring Data Couchbase.

Model (User.java)

@Document
public class User implements Serializable {
   @Id
   private String id;

   @Field
   @NotNull
   private String username;

   @Field
   @NotNull
   private String password;

   @Field
   private List<Devices> deviceList;

   /** getter and setter here **/
}

Model (Devices.java)

@Document
public class Devices implements Serializable {
   @Field
   @NotNull
   private String deviceId;

   @Field
   @NotNull
   private String status;

   @Field
   @NotNull
   private String createdDate;

   @Reference
   private User user;

   /** getter and setter here **/
}

Repository

@Repository
@Transactional
@N1qlPrimaryIndexed
public interface UserRepository extends CouchbaseRepository<User, String>{

   User findOneByUsername(String username);

   User findOneByDeviceId(String deviceId);
}

Document

{
   "username": "username",
   "password": "password",
   "devicesList": [
    {
      "deviceId": "abc123",
      "status": "deactived",
      "createdDate": "2017-07-28 15:59:13"
    },
    {
      "deviceId": "abc456",
      "status": "actived",
      "createdDate": "2017-07-28 15:59:13"
    },
    {
      "deviceId": "abc789",
      "status": "deactived",
      "createdDate": "2017-07-28 15:59:13"
    }
  ]
}

Result

{
   "responseCode": 200,
   "data": {
      "id": "user-login-03",
      "username": "username",
      "password": "password",
      "deviceList": null
   }
}

I hope you could help me regarding this matter. Thank you in advance

In your class, attribute name is deviceList but in json it is devicesList. The persisted json can not be converted to POJO since the attribute names are different.
