无法按对象id查询对象

在我的云代码中，我试图在保存后立即使用对象id从Parse.com查询对象。由于某些原因，它无法正常工作，我尝试的所有其他带星号的行变体也无法正常工作。我做错了什么？

Parse.Cloud.afterSave("NewMessage", function(leanBody, leanSenderName, leanSenderId, request) {
    var query = new Parse.Query("NewMessage");
    query.get(request.object.id, { *************************************************
        success: function(results) {
            console.log("The first object was retrieved");
            leanBody = (results.get("MessageBody"));
            leanSenderName = (results.get("senderName"));
            leanSenderId = (results.get("senderId"));
            getUsers(leanBody, leanSenderName, leanSenderId);
            results.destroy({
                success: function(results) {
                    console.log("deleted");
                }, error: function(results, error){
                }
            });
        }, error: function(error){
        }
    });
});
