Posting a photo to Facebook - doesn't support blobs?! iOS

Hi guys,

I'm trying to post a picture to facebook, it always used to work just fine but now I get an error saying TiBlob is not a supported format?!

You can see the console output here:

I'm using the 4.0 Beta (4.0.1.201505170721) on Mavericks running on an iPhone 4 running 7.1.2

Here's my code

data = {
        link: "http://www.facebook.com/Game",
        name: "Game",
        caption: "Game",
        picture: blobImage
    };
 
    if (fb.permissions.indexOf('publish_actions') < 0 ){
 
        fb.requestNewPublishPermissions(['publish_actions'], fb.AUDIENCE_FRIENDS, function(p){
 
            if (p.success){
 
                fb.requestWithGraphPath('me/photos', data, 'POST', function(e){
 
                    if (e.success) {
                        addCoins.on(facebookCoins, facebookBonusPost, function(outcome){
                            myAlerts.on("Posted!", "Certificate Posted To Your Page");
                        });
                    } else {
                        myAlerts.stayOn("Oops!", "Something Went Wrong!\nTry Logging Out Of Facebook And Then Log Back In" + e.error);
                    };
                });
 
            } else if (p.cancelled){
                myAlerts.stayOn("Cancelled! :(","You Can't Post Pictures For Your Friends Without Giving Permission!");
            } else {  // Error or anything else
                myAlerts.stayOn("Error! :(", "There is a problem with Facebook!");
            };
        });
 
    } else {  //  Permission already granted
 
        fb.requestWithGraphPath('me/photos', data, 'POST', function(e){
 
            if (e.success) {
                addCoins.on(facebookCoins, facebookBonusPost, function(outcome){
                    myAlerts.on("Posted!", "Certificate Posted To Your Page");
                });
            } else {
                myAlerts.stayOn("Oops!", "Something Went Wrong!");
            };
        });
    };

FWIW This was working just fine on Android, although now I've replaced it with an intent chooser for greater sharing options and the 'blobImage' still works just fine with that.
