Undefined getException method while handling exception in Symfony 5

Question

I created an exception class as follows:

<?php

declare(strict_types=1);

namespace App\Exception;

use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpKernel\Event\ExceptionEvent;
use Symfony\Component\HttpKernel\Exception\HttpException;
use function strpos;

final class HTTPExceptionListener
{
    public function onKernelException(ExceptionEvent $event): void
    {
        $exception = $event->getException();
        if (! ($exception instanceof HttpException) || strpos($event->getRequest()->getRequestUri(), '/api/') === false) {
            return;
        }

        $response = new JsonResponse(['error' => $exception->getMessage()]);
        $response->setStatusCode($exception->getStatusCode());
        $event->setResponse($response);
    }
}

I have added following to my services.yaml file:

 App\Exception\HTTPExceptionListener:
        tags:
            - { name: kernel.event_listener, event: kernel.exception }

But I am getting error:

Attempted to call an undefined method named "getException" of class "Symfony\Component\HttpKernel\Event\ExceptionEvent".

So can't you simply open the ExceptionEvent class and inspect its methods? — Mike Doe

1) open the class 2) notice there's no getException method, the error message is self explanatory 3) look for other methods 4) notice the getThrowable method 5) use getThrowable instead 6) read the docs — Mike Doe

In Symfony 4.4 the getException method was deprecated, and was removed in Symfony 5.

Use getThrowable instead.
