GalleryEmbed::init failure

Hello,

I've gone through the documentation several times, as well as several posts here... but cannot figure out why my GalleryEmbed::init is failing.

Here is how I'm calling it:

    $g2URI = "/mg/";
    $EmbedUri = "/media3.php";
    $uid = $_SESSION['login_id']; // Numeric primary key, e.g. 1,2,3,4,5...
    $uname = $_SESSION['login_user']; // username string, e.g. joebob1
    $level = $_SESSION['login_level']; // numeric group level
    $email = $_SESSION['Email']; // email string
    $fname = $_SESSION['First']; // first name string
    $lname = $_SESSION['Last']; // Last name String
    $FullName = "$fname $lname";



    // initiate G2
    $ret = GalleryEmbed::init(array('g2Uri' => $g2URI, 'embedUri' => $EmbedURI, 'activeUserId' => $uid ));
if ($ret) {
        /* Error! */
        /* Did we get an error because the user doesn't exist in g2 yet? */
        $ret2 = GalleryEmbed::isExternalIdMapped($uid, 'GalleryUser');
        if ($ret2 && $ret2->getErrorCode() & ERROR_MISSING_OBJECT) {
                /* The user does not exist in G2 yet. Create in now on-the-fly */
                $ret = GalleryEmbed::createUser($uid, array('username' => $uname ));
                if ($ret) {
                        /* An error during user creation. Not good, print an error or do whatever is appropriate
                         * in your emApp when an error occurs */
                        print "An error occurred during the on-the-fly user creation <br>";
                        print $ret->getAsHtml();
                        print "uid is $uid<br>";
                        exit;
                }
        } else {
                 /* The error we got wasn't due to a missing user, it was a real error */
                if ($ret2) {
                        print "An error occurred while checking if a user already exists<br>";
                        print $ret2->getAsHtml();
                }
                print "An error occurred while trying to initialize G2<br>";
                print $ret->getAsHtml();
                        print "uid is $uid<BR>";
                exit;
        }

    }

As you can see, it's pretty much line for line from the examples, except it isn't working. If I load the script while I'm not logged in, it will load gallery as a guest user. If I'm logged in as any user. I see this:

An error occurred while trying to initialize G2

uid is 1

The number relating to the missing object error changes based on what user is logged in, but it does not relate to the value stored in $uid, which you can see by the fact that I'm printing out that value when there is an error. (my initial thought was that the variable was broken, but that's not the case since it's showing the actual uid for the user.)

Anyone out there able to help me?

That worked like a charm, thanks!

I actually do have GalleryEmbed::handleRequest() running, I simply failed to include that fact above. My apologies.

I now have one more hurdle to overcome (user groups) and I'll be ready for the 'visual' part of my integration.
