SpringBoot + Thymeleaf: подтвердить адрес электронной почты

У меня есть этот объект:

@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
public class NatalChartDataPayload {
    String langCode;

    @NotEmpty(message = "Email cannot be empty")
    @Email(message = "Invalid email format")
    String email;

    String city;
    String place;
}

Контроллер выглядит так:

@GetMapping({"/data"})
public String data (Model model) {
    model.addAttribute("months", Month.values());
    model.addAttribute("data",   NatalChartDataPayload.builder().build());
    return "natalChartData";
}

@PostMapping("/create")
public String createNatalChart ( 
    @Valid @ModelAttribute NatalChartDataPayload data,
    BindingResult result, 
    Model model
) {        
    if (result.hasErrors()) {
        return "natalChartData";
    }
        
    User user = new User();    
    user.setEmail(data.getEmail());
               
    if (data.getPlace() == null ||
          data.getPlace().isEmpty() ||
          data.getEmail() == null ||
          data.getEmail().isEmpty()) {
    return "redirect:/natalchart/data";
}

Однако, когда адрес электронной почты неверен, у меня возникает эта ошибка:
