SpringBoot + Thymeleaf: подтвердить адрес электронной почты ⇐ JAVA

[Anonymous]

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;
}

и этот контроллер:
@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";
}
..

но если адрес электронной почты неправильный, у меня возникает такая ошибка:
