Hey Everyone,

I am receiving this error: Requires a valid user is specified (either via the session or via the API parameter for specifying the user. when I am trying to utilize Facebook's FB.api with JS SDK for method: users.hasAppPermission

I am constantly receiving this error, for any uid I pass on. Here is my code:

$(document).ready(function() {
    var perms_requested = <?php echo PERMS;?>;
    var user_id = <?=$user_id;?>;
    $('#perms_check').html(loading);
    ask_for_perms(perms_requested, function(data) {
        $('#perms_check').html(data);
    });
    function ask_for_perms(perms_requested,cb) {
        var request = [];
        $.each(perms_requested,function(i,permission) {
            FB.api({
                method: 'users.hasAppPermission',
                ext_perm: permission,
                uid: user_id
                }, function(response) {
                if (response == 0) request.push(permission);
                if (i == perms_requested.length - 1) cb(request.join(', '));
            });
        });
    }
});

Also, I am utilizing nearly the same code in some other part of the same application, and I am getting fine results with that.
