Error: Missing Controller

Error Sitemap.xmlController could not be found.

            strpos($controller'/') !== false ||
            strpos($controller'.') !== false ||
            $firstChar === strtolower($firstChar)
        ) {
            throw $this->missingController($request);
        }
        /** @var class-string<\Cake\Controller\Controller>|null */
        return App::className($pluginPath $controller$namespace'Controller');

In the case you tried to access a plugin controller make sure you added it to your composer file or you use the autoload option for the plugin.

Suggestion Create the class Sitemap.xmlController below in file: src\Controller\Sitemap.xmlController.php

    <?php
    
namespace App\Controller;

    use 
App\Controller\AppController;

    class 
Sitemap.xmlController extends AppController
    
{

    }

If you want to customize this error message, create templates\Error\missing_controller.php
