ACS Sendrequest call not working

I am trying to do a bulk delete for photos with the titanium sdk and I cannot get the send request to run. I get the error "Requested API endpoint does not exist. Check that you are using the correct GET, POST, PUT, or DELETE HTTP method."

i tried it without the created date in case that might have been causing an issue but its the same error. Type is a custom object for my photo. How do i get this to work?

//try to delete old pictures of fish
var twoweeksago = moment().subtract(14, 'days');
    Cloud.sendRequest({
        url : "https://api.cloud.appcelerator.com/v1/photos/batch_delete.json?key=MYAPPKEY&pretty_json=true",
        method : "DELETE",
        data : {
            "Type" : "Fish Pictures",
            "created_at" : {
                "$lte" : twoweeksago
            }
 
        }
    }, function(e) {// The callback called when the request completes
        if (e.success) {
            var photo = e.photo[0];
            Ti.API.info("Success in deleteing all pictures" + JSON.stringify(e));
        } else {
            Ti.API.info('Error deleting all pictures:' + ((e.error && e.message) || JSON.stringify(e)));
        }
    });
