SPRING: validation returning error 500 instead of 400

Why does the validation return an internal server error instead of a bad request when the request does not pass validation? I've seen some videos about validation and in the examples it returned a bad request but in my application its returning error 500, here is my model class

@Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    //@Column(nullable = false, unique = true)
    @NotBlank
    private String username;
    @Column(nullable = false, unique = true)
    private String email;


the post method

@PostMapping
    public ResponseEntity<UserModel> postUser(@Valid
                                              @RequestBody UserDTO userDTO) {

        var user = new UserModel();
        BeanUtils.copyProperties(userDTO, user);
        return ResponseEntity.status(HttpStatus.CREATED).body(userService.save(user));

    }


and this is the error when i send a request with a blank username:

jakarta.validation.ConstraintViolationException: Validation failed for classes [com.vss.wardrober.models.UserModel] during persist time for groups [jakarta.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='must not be blank', propertyPath=username, rootBeanClass=class com.vss.wardrober.models.UserModel, messageTemplate='{jakarta.validation.constraints.NotBlank.message}'}
]
