javascript - 如何解决 "TypeError: callback.apply is not a function"？

Question

我正在做一个大学项目，我已经阅读了关于我的问题的每一篇文章，但我还没有找到解决方案。也许你可以帮我。

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。

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

TypeError: callback.apply is not a function

    at process._tickCallback (internal/process/next_tick.js:98:9)

Process finished with exit code 1

提前谢谢您!

您使用了太多参数。

更改此:

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

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

对此:

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

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