Parse.com推送云代码

Question

我正在尝试为Parse编写一个云代码作业，一旦大学达到50个用户，就会向某个大学的每个人发送推送。我非常确定我正确地编写了代码但是当我运行Job时，推送并没有被发送。有什么想法吗？

Parse.Cloud.useMasterKey();
Parse.Cloud.job("UniUsers", function(request, response) {
var query = new Parse.Query("Universities");
    query.notEqualTo("pushSent", "Yes");
    query.greaterThan("numUsers",49);
    query.first({
        success: function(uniObj){
            var uni = uniObj.get("university");
            var query2 = new Parse.Query("_User");
                query2.equalTo("university", uni);
                query2.limit(50);
                query2.find({
                    success:function(results){

                        for (var i = 0; i < results.length; i++) { 
                            var object2 = results[i];
                            var userid = object2.id;
                                    var thePush = new Parse.Query("_Installation");
                                    thePush.equalTo('user',userid);
                                    Parse.Push.send({
                                    where: thePush,
                                    data:{
                                    aps:{
                                        alert: "Your University Has Been Unlocked! 
Start searching for your Roomie now!",
                                            sound: ""
                                                }
                                                }

                                            });

                            }
                            response.success("Success!");
                    },
                    error:function(error){
                        response.error("Error");
                                                }


                })
        }
    })
