遺漏的類型錯誤：對象＃<Object>有沒有方法「_isNullOrUndefined」

當運行Parse.com的aftersave，我有時得到的錯誤：遺漏的類型錯誤：對象＃<Object>有沒有方法「_isNullOrUndefined」

大多數的時候，有完全沒有問題。

} 
Result: Uncaught TypeError: Object #<Object> has no method '_isNullOrUndefined'

我的一片雲代碼JS

Parse.Cloud.beforeSave('Messages', function(request, response){ 
    if(request.object.isNew()){ 
     // FIRST, Set the current score 
     var last_score = request.user.get('last_score'); 
     request.object.set('score', last_score); 
     cl('Beforesave: added score'); 

     // SECOND, let the receiver know 
     var from_id = request.object.get('from').id; 
     var to_id = request.object.get('to').id; 
     var message = request.object.get('from').get('first_name') + ': ' + request.object.get('message'); 
     var action = 'new_message'; 
      send_push_message(from_id, to_id, message, action); 
     cl('Beforesave: send message'); 
    } 
    response.success(); 
});

奇怪這是我甚至不使用的方法「_isNullOrUndefined」。

有同樣的問題。在afterSave，beforeSave觸發器和雲功能中的某些時間發生。 – bartl
