Run a Project on Browser from IntelliJ IDE

I have opened a project that I downloaded in IntelliJIDEA IDE. The project structure is as follows. I am trying to run the userAuthenticationController.php controller's index() method to view the login page.

According to this project's config.php File, the base_url is provided as follows.

config.php

$config['base_url'] = 'http://localhost:9080/Internship-Management/Sourcecode/Codeigniter/';

I tried running this address in Chrome but am getting the following error.

userAuthenticationController.php

// Show login page
public function index() {
$this->load->view('login/loginView');
}

routes.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
|   example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
|   https://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are three reserved routes:
|
|   $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
|   $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router which controller/method to use if those
| provided in the URL cannot be matched to a valid route.
|
|   $route['translate_uri_dashes'] = FALSE;
|
| This is not exactly a route, but allows you to automatically route
| controller and method names that contain dashes. '-' isn't a valid
| class or method name character, so it requires translation.
| When you set this option to TRUE, it will replace ALL dashes in the
| controller and method URI segments.
|
| Examples: my-controller/index -> my_controller/index
|       my-controller/my-method -> my_controller/my_method
*/
$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

Do I need to change the path that I am using to load the controller in my browser?

Any suggestions in this regard will be highly appreciated.
