'Missing ErrorController interface in Spring Boot

I am trying to implement a custom replacement for the Whitelabel error page in a Spring Boot application using Spring 5.3.15 and Java 17.

According to the many tutorials I found it should be trivial:

Implement a custom controller that implements the ErrorController interface
A method with a request mapping for /error
Design an attractive error.jsp page.

I have spring-boot-starter-web in my POM and I see all other Spring MVC classes, but there is no ErrorController interface in my classpath.

What am I missing? Has Spring changed and there is a new way to implement a generic custom error page?

NOTE: Code not yet included to avoid noise. EDIT: Added some relevant code per OAPiet's request.

EDIT: I located the current spring-boot-autoconfigure.jar and navigated to org.springframework.boot.autoconfigure.web, the package that is supposed to contain ErrorController.class and it is not there. I think this indicates that the approach for creating a custom error page has indeed changed.

Code pieces:

SpringConfig (all of the relevant configuration is here, application.properties does not yet contain anything related to the error page:

@Configuration
@EnableAutoConfiguration(exclude= {DataSourceAutoConfiguration.class})
@ComponentScan(basePackages= {"my.app.pkg", "my.error.controller.pkg"})
@PropertySources({
  @PropertySource(value="classpath:application_PROD.properties", ignoreResourceNotFound=true),
  @PropertySource(value="classpath:application_DEV.properties", ignoreResourceNotFound=true),
})
public class SpringConfig {
  @Bean
  public InternalResourceViewResolver resolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setViewClass(JstlView.class);
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
  }
}

MyErrorController (Just a skeleton for now. I want a controller so that I can supply additional values to display in the error.jsp page. Problem is that the ErrorController interface has either been moved or removed.):

@Controller
public class MyErrorController implements WebUtils, JsonUtils {
  @RequestMapping(value={"/error"}, method=RequestMethod.GET)
  public String unexpectedErrors(Model model, HttpServletRequest request) {
    Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");
    Exception exception = (Exception) request.getAttribute("javax.servlet.error.exception");
    
    model.addAttribute("statusCode",              statusCode);
    model.addAttribute("exception",               exception);
    return "err";
  }
}

As requested, adding a screenshot of spring-boot-autoconfigure-2.6.3.jar showing the org.springframework.boot.web.servlet.error package where ErrorController should be but isn't.

Also, here is my POM:

Solution 1:^[1]

Add this configuration in: application.properties

# Disable the white label error page
server.error.whitelabel.enabled=false


# If you need to mapping in a result of a rest services
server.error.path=/error

The HTML error page have to be in resources/templates/error.html

For JSP page: webapp/WEB-INF/views/error.jsp

In application.properties:

spring.mvc.view.prefix= /WEB-INF/views/
spring.mvc.view.suffix= .jsp

It would be very helpful if you show some code for helping you.
