Discord.JS bot on heroku-CodePudding

Yesterday I've created a Discord bot using Discord.JS and it's working properly when I'm using my bot locally but after hosting it on Heroku it's not working anymore and the bot is offline. In Heroku logs I can see this:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

I completely don't know what is the reason for that error. If anyone could help me I would be glad

Your questions was already answered in another question. Answer by Nick Parsons. Basically, you have to change your node version.
