Symfony: sending a jsonResponse

Question

I am working on a symfony application, and I am trying to delete a remember me cookie, using the following code:

$response->headers->clearCookie($cookieName,'/');

I have to call the response->send() method for this to take effect, this works perfectly with a simple response, but when i try to use it with a jsonResponse, the function send() returns this error:

JSON.parse: unexpected non-whitespace character after JSON data

There is nothing wrong with my json data, even if i specify no data it seems that send function is just not working with a jsonResponse

Here is my code for the jsonResponse :

$array = array('message'=>'your account is disabled','success'=>false);
$response = new JsonResponse($array);
$response->send(); //this triggers the error

Your help will be appreciated !

It probably won't change anything, but you should return $response in action instead of calling send() method directly. — Jakub Matczak

Are you sure it's a PHP related error? I have seen this error on Javascript side. — felipsmartins

Jakub if i return the response it doesn't clear the cookie, so i have to use the send method which generate this error, and adding the return response wony change a thing, — ZeSoft

Can you try doing a var_dump or similar on $response before the send to see what it looks like? I'm wondering what the no-whitespace character might be. I may have seen something like this before. Update your post to show what it prints out. — Alvin Bunk

your can use this code in controller

$array = array('message'=>'your account is disabled','success'=>false);
return new JsonResponse($array);

Send, in controller is not valid and you can use return in controller.
