spring boot project and com.microsoft.sqlserver.jdbc.SQLServerException: The "variant" data type is not supported

Question

Using this link - https://dzone.com/articles/configuring-spring-boot-for-microsoft-sql-server

I created a simple spring boot project to create a table in MSSQL version 13.0.5865.1 and getting the below error:

2021-03-02 15:01:14.362  INFO 3116 --- [           main] com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Start completed.

Any idea whats the issue?

Here are all my classes and pom.xml

Main class

package com.termine.mssqldb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MssqldbApplication {

    public static void main(String[] args) {
        SpringApplication.run(MssqldbApplication.class, args);
    }

}

User class

package com.termine.mssqldb;

import javax.persistence.*;

@Entity
@Table(name = "user_tbl")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)

    private Integer id;
    private String name;
    private int age;

    public User() {
    }
    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                ", name='" + name + '\'' +
                ", Age=" + age +
                '}';
    }
}

UserRepository

package com.termine.mssqldb;

import com.termine.mssqldb.User;
import org.springframework.data.repository.CrudRepository;

public interface UserRepository extends CrudRepository<User, Integer> {
    User findByName(String name);
}

Spring Boot Connect to Microsoft SQL Server Examples.

Use this dependency definition for the SQL Server JDBC Driver.

<dependency>
   <groupId>com.microsoft.sqlserver</groupId>
   <artifactId>mssql-jdbc</artifactId>
   <scope>runtime</scope>
</dependency>
