Function decodeJwt completely destroy my $_ENV variable

I did everything according to this tutorial and I still have a problem with the decodeJwt() function. Especially in this part: request()->cookies->get('access_token'),

function decodeJwt($prop = NULL) {

\Firebase\JWT\JWT::$leeway = 1;
$jwt = \Firebase\JWT\JWT::decode(

if ($prop === NULL) {
    return $jwt;

return $jwt->{$prop};


Everytime, I set user variable: $user = findUserByAccessToken(); it returns me Fatal Error that says Key is probably empty. (Fatal error: Uncaught InvalidArgumentException: Key may not be empty).

So I tried to dump my $_ENV variable before setting $user variable and I get my SECRET_KEY, COOKIE_DOMAIN and everything stored in $_ENV variable like REMOTE_ADDR etc... so it's alright. However when I try to do the same after setting $user variable, $_ENV variable is completely empty (everything) and this will be probably the issue why I'm getting "Key may not be empty" error. Could someone help me or advise why this is happening? Thanks
