Implement a custom error controller in Symfony 4.4

Question

What i have done:

I have created this custom controller cause I want to pass to the error pages some extra variables.

#Controller/CustomErrorControler.php
namespace App\Controller;

use App\Controller\Base\BaseController;
use Symfony\Component\ErrorHandler\Exception\FlattenException;
use Symfony\Component\HttpKernel\Log\DebugLoggerInterface;

class CustomErrorController extends BaseController
{

    public function show(FlattenException $exception, DebugLoggerInterface $logger = null)
    {
        return $this->getView('bundles/TwigBundle/Exception/error.html.twig', [
            "code" => $exception->getStatusCode(),
            "message" =>$exception->getStatusText()
        ]);
    }
}

and the enabled

#config/packages/framework.yaml
error_controller: App\Controller\CustomErrorController::show

I have followed the documentation directly. My problem is that I need, for non-production stages to get the default exception templates provided by the framework.

I have tried to extend Symfony\Component\HttpKernel\Controller\ErrorController but I'm getting errors for autowiring.

Maybe I should use Symfony\Component\ErrorHandler\ErrorRenderer\ErrorRendererInterface Any ideas how to implement this?

Solved it by using different framework.yaml for Prod

If you want to use your custom controller only in production you can modify your config/packages/framework.yaml file by adding the when clause, like this:

when@prod:
    framework:
        error_controller: App\Controller\CustomErrorController::show

This will ensure that your custom error controller is only used in the production environment, while the default exception templates are used in other environments
