TypeError: Cannot read property 'message' of undefined - Twitter API

Question

下面是运行 app.js 时的输出。当一切正常时，这开始完全随机发生。绝对没有任何改变。

 TypeError: Cannot read property 'message' of undefined
        at /home/ec2-user/environment/rt-bot/app.js:78:48
        at Request._callback (/home/ec2-user/environment/node_modules/twitter/lib/twitter.js:220:14)

我已经尝试从我的 master 分支创建新实例（自上次工作以来没有提交），甚至仍然出现此错误。有什么想法吗？

导致错误的代码，尽管此代码之前有效。

T.get('search/tweets', query, function(err, data, response) {
  // continue if no errors
  if(!err){
    // loop
    for(let i = 0; i < data.statuses.length; i++){
      // get latest tweet ID
      let id = { id: data.statuses[i].id_str }

      // try favorite
      T.post('favorites/create', id, function(err, response){

        // log failures
        if(err){
          console.log('Try Favorite - ', err[0].message);
        }

        // log success
        else{
          let username = response.user.screen_name;
          let tweetId = response.id_str;
          console.log('Favorited: ', `https://twitter.com/${username}/status/${tweetId}`)
        }

      });

第一次出现的图像。如您所见，一切正常，然后这个错误不知从何而来，完全没有对环境或代码库进行任何更改。

更新：

使用 console.log('Try Favorite - ', err.message); 而不是 console.log('Try Favorite - ', err[0].message);

记录错误时的输出

[[Apr 28 21:27:00.702]] [LOG]   Try Favorite -  HTTP Error: 429 Too Many Requests
[[Apr 28 21:27:00.705]] [LOG]   Try Favorite -  HTTP Error: 429 Too Many Requests

[[Apr 28 21:27:00.793]] [LOG]   Try Favorite -  HTTP Error: 429 Too Many Requests

另请注意，转发功能使用相同的控制台日志记录方法。请参阅下面的代码，并输出正常。

// try retweet
      T.post('statuses/retweet', id, function(err, response){

        // log failures
        if(err){
          console.log('Try Retweet - ', err[0].message);
        }

Twit uses request 向 Twitter API 发送 HTTP 请求，因此错误将是单个对象而不是数组，因此您的错误处理程序将类似于

if(err){
  console.log('Try Favorite - ', err.message);
}
