我正在写一个不和谐的机器人。 我的discord bot怪异地工作的一部分是当我执行此特定语句时：
currentAnagramAnswer = movielist[Math.floor(Math.random() * movielist.length)].toLowerCase().split(" ").join('');
其中movielist是约250个电影（字符串）的数组，通过读取文件来填充。
现在，当我在本地运行此代码时，我得到了期望的结果-从数组中随机选择一个元素。但是，当我将其推送到heroku然后从heroku运行时，它不仅返回一个元素，而且还返回了我所有的元素（小写，根据上述定界符拆分并再次加入）
注意：我使用readFileSync来填充数组。我也尝试使用async await，但实际上并不能解决问题。
编辑：当我打印currentAnagramAnswer时，heroku日志显示此内容

我的readMovieList在另一个文件中
const readMovieList = (movieLoc) => {
try{
var movie = fs.readFileSync(movieLoc, 'utf8');
movieListArr = movie.split('\r\n');
return movieListArr;
}
catch(e){
console.log("Error reading file: ", e.stack)
