new (Json)Response shows blank page (Symfony HttpFoundation)

Question

I am using the HttpFoundation in my small project: use \Symfony\Component\HttpFoundation\JsonResponse as JsonResponse;

Unfortunately all my responses (tried JsonResponse, Response and BinaryFileResponse) only return a blank page, no errors and the code gets executed normally, e.g.

/* Get Inputs */
if (!$data = filter_input(INPUT_GET, 'url', FILTER_VALIDATE_URL)) {
    return new JsonResponse(array(
        'result' => 'error',
        'message' => 'URL is invalid or missing'
    ));
}else{
     return new JsonResponse(array(
        'result' => 'success',
        'message' => 'FINE'
    ));

There are no errors in the logs either.

Any ideas how to approach the issue?

//UPDATE FOR CLARIFICATION

$json = new JsonResponse(array(
    'result' => 'error',
    'message' => 'Encrypt is invalid or missing'
));

echo $json;

returns HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: application/json {"result":"error","message":"Encrypt is invalid or missing"}

but why does the return not work?

what if you echo the response? Are you invoking the service via Ajax? — GuyT, Dec 21 '15 at 08:44
display_errros is on. `$json = new Json Response...` and then `echo $json` returns `HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: application/json {"result":"error","message":"Encrypt is invalid or missing"}` so there is seomthing wrong with the `return` statement? — PrimuS, Dec 21 '15 at 09:00
Which framework? Apparently your application does not handle `Response` objects returned from the controller. — Alex Blex, Dec 21 '15 at 09:05
Well, not using a full stack framework, but the Response I get with this: `use \Symfony\Component\HttpFoundation\JsonResponse as JsonResponse;` — PrimuS, Dec 21 '15 at 09:22

You're not using the full stack framework, so you need to be sure that your front controller or equivalent calls $response->send(); to deliver the response to the client.

It's addition to answer:

$response = new JsonResponse(array(
    'result' => 'error',
    'message' => 'Encrypt is invalid or missing'
));
$response->send();
