No serializer found for class org.hibernate.proxy.pojo.byte.ByteBuddyInterceptor (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS - spring-boot

Question

I am trying to pull features of a product using hibernate API in Spring Boot application.
Feature.java
#Entity
#Table(name = "feature")
#JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
public class Feature extends BaseEntity {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(generator = "UUID")
#GenericGenerator(
name = "UUID",
strategy = "org.hibernate.id.UUIDGenerator"
)
#Column(name = "id", updatable = false)
private String id;
#Column(name = "name")
private String name;
#Column(name = "code", updatable = false)
private String code;
#OneToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "product_id", referencedColumnName = "id")
private Product product;
// getters & setters
}
#Entity
#Table(name = "product")
public class Product extends BaseEntity {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(generator = "UUID")
#GenericGenerator(
name = "UUID",
strategy = "org.hibernate.id.UUIDGenerator"
)
#Column(name = "id", updatable = false)
private String id;
#Column(name = "name")
private String name;
#Column(name = "code", updatable = false)
private String code;
// getters & setters
}
when i call below method in Rest Controller class
#GetMapping("/list/{productId}")
public ResponseEntity<List<Feature>> retrieveList(#PathVariable("productId") String productId) {
List<Feature> featureList = featureService.retrieveListByProductId(productId);
return new ResponseEntity<>(featureList, HttpStatus.OK);
}
#Override
#Transactional
public List<Feature> retrieveListByProductId(String productId) {
return featureRepo.retrieveListByProductId(productId);
}
#Override
public List<Feature> retrieveListByProductId(String productId) {
Session session = sessionFactory.getCurrentSession();
String queryString = "from Feature f where f.product.id = :productId order by f.name";
Query<Feature> query = session.createQuery(queryString, Feature.class);
query.setParameter("productId", productId);
return query.getResultList();
}
i am getting

I added below property in Spring Boot(2.7.5)
spring.jackson.serialization.fail-on-empty-beans=false
in application.properties file. But still, it is throwing an exception.
I also tried by changing from FetchType.LAZY to FetchType.EAGER. Though it is working, i want to load product lazyly.
I tried the post. Still getting the same error
Can someone help me to fix it
