  "description": "",
  "main": "bot.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@discordjs/voice": "^0.8.0",
    "moment.js": "^2.29.1",
    "discord.js": "^13.6.0",
    "init": "^0.1.2"
  }
}

You are depending on moment.js, but the correct package is just moment.

Did you manually add that to your package.json? First, remove that line.

Then add the correct package:

If you are using Yarn, run yarn add moment
If you are using NPM, run npm install moment

This should install the dependency locally and also add it to your package.json and the relevant lock file. Commit the changes to those files and redeploy.

You should place the node_modules folder in your root directory
