Класс контроллера, в котором этот метод вызывается

@Controller
public class HomeController {
    private final LoginManagerService loginManagerService;
    private final ClientDAOImpl clientDAOImpl;
    @Autowired
    public HomeController(LoginManagerService loginManagerService, ClientDAOImpl clientDAOImpl) {
        this.loginManagerService = loginManagerService;
        this.clientDAOImpl = clientDAOImpl;
    }

    @GetMapping("/home")
    public String home(HttpSession httpSession, Model model, @RequestParam(required = false) String Logout){
        if (Logout != null){
            loginManagerService.setEmail(null);
        }
        String username = (String) httpSession.getAttribute("username");
        ClientDetails clientDetails = clientDAOImpl.findByUsername(username);
        String email = clientDetails.getClient().getEmail();
        String id = clientDetails.getClient().getBankAccount().getId().toString();
        String firstName = clientDetails.getClient().getFirstName();
        String lastName = clientDetails.getClient().getLastName();
        String balance = String.valueOf(clientDetails.getClient().getBankAccount().getAccountBalance());
        model.addAttribute("email", email);
        model.addAttribute("firstName", firstName);
        model.addAttribute("lastName", lastName);
        model.addAttribute("id", id);
        model.addAttribute("balance", balance);
        return "home";
    }
}

Сущность ClientDetails

@Getter
@Setter
@Table(name = "clients_details")
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Entity
public class ClientDetails{
    @Column(name = "id")
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long ID;
    @Embedded
    private Client client;
}

Встроенный класс Client также имеет корректное поле String username, все имена проверены(для экономии места не стал выкладывать) Класс HibernateConfig

@Configuration
public class HibernateConfig {
    @Bean
    public Session getSession(){
        SessionFactory factory = new org.hibernate.cfg.Configuration().configure("hibernate.cfg.xml")
                .addAnnotatedClass(ClientDetails.class).buildSessionFactory();
        return factory.openSession();
    }
}

И главный класс запуска приложения

@SpringBootApplication
public class BankServiceApplication {

    public static void main(String[] args) {
        System.setProperty("javax.xml.bind.context.factory", "org.eclipse.persistence.jaxb.JAXBContextFactory");
        SpringApplication.run(BankServiceApplication.class, args);
    }
}

Стоит сказать, что я пытался проверить в debug-режиме, приходит ли атрибут username в метод findByUsername и да, этот параметр приходит, но, после длительного рассмотрения процесса каждого метода(на стороне Spring и Java) почему-то, далее в этот метод поступает null. Из-за обилия вызовов сторонних классов я не могу заметить, в какой момент username теряет значение, но точно могу сказать, что происходит это после строки session = session.getSession();.
