<?php

For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 22 and the first side effect is on line 20.

You have injected the Request via parameter $request. This is generally not recommended as there might be multiple instances during a request cycle (f.e. when using sub-requests). Instead, it is recommended to inject the RequestStack and retrieve the current request each time you need it via getCurrentRequest().

    {
        $this->container->enterScope('request');
        $this->container->set('request', $request, 'request');
        $this->container->get('request_stack')->push($request);

        if ($request->attributes->get('_defaultHandler')) {
            return parent::handle($request, $type, $catch);

It seems like you call parent on a different method (handle() instead of handleRaw()). Are you sure this is correct? If so, you might want to change this to $this->handle().
