Symfony Production Mode Error Reports and POST values

Question

I'm using Symfony 4 but I expect this is much the same for 2 and 3 too.

Production Mode error reports from the swift monolog handler return the complete request URL for GET requests, so it's fairly easy to reproduce the error in development.

But, if it's a POST request, you're in trouble as no POST values are provided.

I've had a dig around in the error handling and logging components but nothing is immediately obvious.

Has anyone else come across this problem and found a fix for it?

Based on a comment from @Puya Sarmidani... this is what I did in the end:

config/services.yaml:

App\Services\MonologExtraProcessor:
    tags:
        - { name: monolog.processor }
        - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }

src/Services/MonologExtraProcessor.php:

namespace App\Services;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;

class MonologExtraProcessor
{
    private $postParams = null;

    public function __invoke(array $record)
    {
        if ($this->postParams !== null) {
            $record['extra']['postParams'] = $this->postParams;
        }
        return $record;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $postParams = $event->getRequest()->request->all();
        $this->postParams = empty($postParams) ? null : serialize($postParams);
    }
}
