Symfony onKernelRequest headers->set dont received on @Route

Question

I have functionm onKernelRequest when i want to add some custom header(in my case api=true||$request->headers->set('api', "true")) and in all Request $request i can get that header but when i try it on annotation its fail:

• onKernelRequest:

public function onKernelRequest(RequestEvent $event)
{
    if (!$event->isMasterRequest()) { return; }

    $request = $event->getRequest();
    $request->headers->set('api', "true");
    return;
}

• Route

/* @Route(
 *     "/user/info/",
 *     name="get_user_info",
 *     methods={"GET"},
 *     condition="request.headers.get('api')"
 * )

• Error

Path almost matches, but Condition "request.headers.get('api')" does not evaluate to "true"

The router listener is being called before your listener.

The router [https://github.com/symfony/http-kernel/blob/master/EventListener/RouterListener.php#L158](listener listen has a priority of 32) where as your listener has a priority of 0 (the default).

If you set your listener to have a higher priority than the router listener it should work.

_{An example using YAML}

services:
    App\EventListener\YourListener:
        tags:
            -
                name: kernel.event_listener
                event: kernel.request
                priority: 40
