My discord bot runs on my computer when I use node index.js but when I do the same thing in the heroku terminal I get the following error which is odd because ./commands is a folder in the connected github and it's working fine on my computer.
node:internal/fs/utils:344
throw err;

It's because you are probably calling the Heroku script from a lower folder - the fs file system runs relative to the current working directory and not relative to the script you called. The solution is to make the path absolute:
fs.readdirSync(path.resolve(__dirname, './commands'))
