如何解决“TypeError: callback.apply is not a function"? [英] How to solve "TypeError: callback.apply is not a function"?

问题描述

我正在做一个大学项目，我已经阅读了所有关于我的问题的帖子，但我还没有找到解决方案.也许你可以帮我.

I am doing a university project and I've read every post regarding my problem, but I am yet to find a solution. Maybe you can help me out.

代码如下:

viewerObj.update({_id: currentIDViewerVar} , {minutesWatched: 5},{upsert:true}  , function (err,result) {
                                            
          if (err) throw err;
          console.log("Viewer " + userNameVar + " gespeichert");
          console.log("minsWatched" +minsWatched);
});

我收到以下错误.我看不出我做错了什么.

I get the following error. I can't see what I am doing wrong.

events.js:160
      throw er; // Unhandled 'error' event
      ^

先谢谢你！

推荐答案

您使用的参数过多.

改变这个:

viewerObj.update({_id: currentIDViewerVar} , {minutesWatched: 5},{upsert:true}  , function (err,result) {

      if (err) throw err;
      console.log("Viewer " + userNameVar + " gespeichert");
      console.log("minsWatched" +minsWatched);
});

为此:

viewerObj.update({_id: currentIDViewerVar, minutesWatched: 5}, {upsert:true}, function (err,result) {

      if (err) throw err;
      console.log("Viewer " + userNameVar + " gespeichert");
      console.log("minsWatched" +minsWatched);
});
