oauth2-client: Not getting all the information from Github API.

For some reason I cannot get the email of my GitHub.

I tried to dig in the code did not find anything.

I even added the scope:

public $scopes = array('user:email');

I also tried:

public $scopes = array('user');

I get NULL.

It also seems that other information are not loading:

string(3) "uid"
int(--------) -> this works but I hid it.
string(8) "nickname"
string(5) "jnbdz"
string(4) "name"
string(19) "Jean-Nicolas Boulay"
string(9) "firstName"
NULL
string(8) "lastName"
NULL
string(5) "email"
NULL
string(8) "location"
NULL
string(11) "description"
NULL
string(8) "imageUrl"
NULL
string(4) "urls"
array(2) {
  ["GitHub"]=>
  string(18) "http://github.com/"
  ["Blog"]=>
  NULL
 }
