I have been working on a discord bot that is working fine when run locally, but it is crashing when hosted on heroku.

• I tried to create a Procfile with the following line: worker : node bot.js
• I also checked in heroku resources, disabled web and enabled the worker dyno.
• I have not exceeded the 550 hour monthly limit.

This is the package.json:

{
  "name": "randomizerbot",
  "version": "1.0.0",
  "description": "",
  "main": "bot.js",
  "scripts": {
    "start": "node bot.js"
  },
  "engines": {
    "node": ">=16.6.0"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "discord.js": "^13.6.0",
    "dotenv": "^16.0.0",
    "nodemon": "^2.0.15"
  }
}

This is my file structure:

This is the error log:

Is there something that I am missing? Thanks in advance.
