我有一个用Snoowrap和Snoostorm用Nodejs编写的reddit机器人，并已部署到Heroku。 我的日志不断提示该错误：

这是我的app.js文件：

initCommentStream();
initPostStream();
initInboxStream();
initModMailStream();
webController = controller;
return module.exports
}
function configReddit(){
r.config({continueAfterRatelimitError: true});
console.info("Finished Reddit configuration.")
}
function watchRateLimit(){
//WATCH JS
// var watch = WatchJS.watch;
// var unwatch = WatchJS.unwatch;
// var callWatchers = WatchJS.callWatchers;
WatchJS.watch(r, "ratelimitRemaining",
() => {
if(r.ratelimitRemaining < 50){
console.warn("Rate limit remaining:" +r.ratelimitRemaining);

}
});
}
function initCommentStream(){

async function notifyNewPost(peopleList, post){

sendFunction(peopleList, post);
}else{
for (const people of peopleList) {
sendFunction(people, post);
}
}
}
module.exports={
initializeBot,
r
}
这是web.js：
const controller = {};
var express = require('express');
var app = express();
const wakeDyno = require("woke-dyno");
const bot = require("./app").initializeBot(controller);
var http = require('http').createServer(app);
var io = require('socket.io')(http);
var port = process.env.PORT || 3000;
app.get('/', function(req, res){
res.sendFile(__dirname + '/html/index.html');
});
io.on('connection', function(socket){
console.log('a user connected');
});
http.listen(port, ()=>{
wakeDyno("https://gas-lighter-bot.herokuapp.com/").start();
console.log('listening on *:'+port);
});
controller.broadcast = (msg) => {
io.emit("ratelimitChanged",msg);
};
奇怪的是，日志没有告诉我错误源于我的代码，所以我有点头绪。 我已经在计算机上运行了几个小时，但是当部署到Heroku时，它在大约1分钟后引发了此错误...。
请帮助：（
编辑：这是错误对象，对我没有帮助，但是也许它将帮助您解决这个问题:(
