and this is my main class:

package io.javabrains.springbootstarter;

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

@SpringBootApplication
public class CourseApiApp {

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

}
javaspringspring-boot

I have also faced the same issue. I am also studying from the same channel. Replace "1.4.2" version with "2.1.0" and update the maven project and run the code. It will work.
