Validation not working Spring Boot, Spring in Action excercise

I am following along with a chapter exercise in Spring in Action the chapter goes through validation but even when I POST the forms with empty input it does not return any form of validation errors! No matter what I do I cannot trigger a validation error response, the form is just accepted as it is completely empty.

Full project @ https://github.com/AdrianLarssonGit/tacoworld/tree/master/tacoworld

Below is what I assume is the relevant code:

OrderController.java:

package com.tacoworld;

import lombok.extern.slf4j.Slf4j;

import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.Errors;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import com.tacoworld.TacoOrder;

@Slf4j
@Controller
@Validated
@RequestMapping("/orders")
public class OrderController {

    @GetMapping("/current")
    public String orderForm(Model model) {
        model.addAttribute("tacoOrder", new TacoOrder());
        return "orderForm";
    }
    
    @PostMapping
    public String processOrder(@Valid TacoOrder tacoOrder, Errors errors) {
        if(errors.hasErrors()) {
            return "orderForm";
        }
        else {
            log.info("Order submitted: " + tacoOrder);
            return "redirect:/";
        }
        
        
    }
}

</form>
</body>

TacoOrder.java:

package com.tacoworld;

import java.util.List;

import javax.validation.constraints.Digits;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.Pattern;

import org.hibernate.validator.constraints.CreditCardNumber;

import java.util.ArrayList;
import lombok.Data;


@Data
public class TacoOrder {

    private String deliveryName;

    private String ccNumber;
    @Pattern(regexp="^(0[1-9]|1[0-2])([\\/])([1-9][0-9])$",message="Wrong pattern MM/YY is needed")
    private String ccExpiration;
    @Digits(integer=3, fraction=0,message="Invalid CCV")
    private String ccCVV;
    
    private List<Taco> tacos = new ArrayList<>();

    
    public void addTaco(Taco taco) {
        this.tacos.add(taco);
        }
}

I am using Spring Boot so have not done much of POM editing except for trying to solve this particular problem, I attach it here anyway for reference:
