I am upgrading an app from an older version of Spring (4) to Spring 6 and Spring Boot from 2.* to 3.2.5. It compiles, but I cannot run it due to the following stack trace:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: UUID
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1786) ~[spring-beans-6.1.6.jar!/:6.1.6]

    // Additional stack trace

Below is my pom.xml file content:

The only class where UUID is used is in the RegisterController. Here’s the relevant part of that class:

package com.spring.bioMedical.Controller;

import java.util.Map;
import java.util.UUID;
import javax.servlet.http.HttpServletRequest;
import jakarta.validation.Valid;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import com.nulabinc.zxcvbn.Strength;
import com.nulabinc.zxcvbn.Zxcvbn;
import com.spring.bioMedical.entity.User;
import com.spring.bioMedical.service.EmailService;
import com.spring.bioMedical.service.UserService;

@Controller
public class RegisterController {
    // Methods with @RequestMapping annotations
}

Can anyone help identify why this error occurs and how to fix it?
