Spring redis return 500 stackoverflow error

Question

I am trying to save some data to Redis in spring boot application.I am getting stackoverflow error while trying to insert the data into Redis.

I know there is some repetitive process going on here, but really couldn't understand where is the exception and the root cause for this.

RedisRepo:

public interface RedisRepo extends CrudRepository<RedisEntity,String> {

}

RedisObj:

public class RedisObj {

    @Id
    private Long field1;

    private String field2;

    private String field3;

    private String field4;

    private String field5;

    private UUID field6;

    private String field7;

    private String field8;

    private MyObject field9;

}

From Service:

redisRepo.save(ObjToRedis);

Exception:

Any suggestions are helpful.

The problem here is, I am using the hiberante entity Object, (which is "MyObject" from the Post). Created a new Object and it worked Fine.
