Deprecated: Use of `BaseErrorHandler` and subclasses are deprecated. Upgrade to the new `ErrorTrap` and `ExceptionTrap` subsystem. See https://book.cakephp.org/4/en/appendices/4-4-migration-guide.html /home/theiitianshub/demo.theiitianshub.com/apiengine2.home-tution.com/config/bootstrap.php, line: 127 You can disable all deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED`. Adding `config/bootstrap.php` to `Error.ignoredDeprecationPaths` in your `config/app.php` config will mute deprecations from that file only. in /home/theiitianshub/demo.theiitianshub.com/apiengine2.home-tution.com/vendor/cakephp/cakephp/src/Core/functions.php on line 321

Cake\Http\Exception\MissingControllerException
Toggle Vendor Stack Frames

Error PagesController could not be found.

     * @return \Cake\Http\Exception\MissingControllerException
     */
    protected function missingController(ServerRequest $request)
    {
        return new MissingControllerException([
            'class' => $request->getParam('controller'),
            'plugin' => $request->getParam('plugin'),
            'prefix' => $request->getParam('prefix'),
            '_ext' => $request->getParam('_ext'),

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 PagesController below in file: src/Controller/PagesController.php

    <?php
    
namespace App\Controller;

    use 
App\Controller\AppController;

    class 
PagesController extends AppController
    
{

    }
