CakePHP 3.x catch selected controller from logging if MissingControllerException occurs - cakephp

Question

In CakePHP 3.x how can I catch selected controller names from logging in error.log file if MissingControllerException occurs.
Currently I am having loggs e.g.:
2022-02-17 09:32:34 Error: [Cake\Routing\Exception\MissingControllerException] Controller class AAA could not be found.
I tried to write own MyExceptionRenderer.php in src/Error folder:
namespace App\Error;
use Cake\Error\ExceptionRenderer;
class MyExceptionRenderer extends ExceptionRenderer{
public function missingController($error){
// Logic if AAA occuress do sth, e.g. redirect to selected page
}
}
In app.php I added:
'Error' => [
'errorLevel' => E_ALL & ~E_DEPRECATED,
'exceptionRenderer' => 'App\Error\MyExceptionRenderer',
'skipLog' => [],
'log' => true,
'trace' => true,
],
But it does not work

As mentioned in the comments, I don't see anything wrong with shown code, I've tried it 1:1 and it works fine for me using CakePHP 3.10.2, the missingController() method is being invoked as expected.
If your renderer is being used, but the method is not being invoked, then you'll have to debug the core exception renderer that you're extending, and figure out what exactly is happening when \Cake\Error\ExceptionRenderer::_customMethod() should be invoked.
That being said, I'd probably use a custom middleware for this instead, as you're not actually going to do exception rendering. Put it after the error handler middleware and catch the exceptions that you want to catch, something along the lines of this:
// in src/Middleware/MissingControllerHandlerMiddleware.php
namespace App\Middleware;
use Cake\Routing\Exception\MissingControllerException;
use Cake\Utility\Hash;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
class MissingControllerHandlerMiddleware
{
/**
* Invoke method.
*
* #param \Psr\Http\Message\ServerRequestInterface $request The request.
* #param \Psr\Http\Message\ResponseInterface $response The response.
* #param callable $next Callback to invoke the next middleware.
* #return \Psr\Http\Message\ResponseInterface A response
*/
public function __invoke(ServerRequestInterface $request, ResponseInterface $response, $next)
{
try {
return $next($request, $response);
} catch (MissingControllerException $exception) {
$class = Hash::get($exception->getAttributes(), 'class');
if ($class === 'AAA') {
return $response->withHeader('Location', 'https://example.com/missing-aaa-controller-redirect');
}
if ($class === 'BBB') {
// ...
}
// ...
throw $exception;
}
}
}
// in src/Application.php
public function middleware(MiddlewareQueue $middlewareQueue): MiddlewareQueue
{
$middlewareQueue
->add(new ErrorHandlerMiddleware(Configure::read('Error')))
->add(new \App\Middleware\MissingControllerHandlerMiddleware())
// ...
return $middlewareQueue;
}
