[paulogdm]

@now/node-server has been deprecated in favor of @now/node

You can also remove a great portion of your configuration file from:

{
  "version": 2,
  "name": "djproducerbot",
  "alias": [
    "djproducerbot.now.sh"
  ],
  "public": true,
  "builds": [
    {
      "src": "index.js",
      "use": "@now/node-server",
      "config": {
        "includeFiles": [
          "binaries/**",
          "audios/**"
        ]
      }
    }
  ],
  "routes": [
    {
      "headers": {
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS",
        "Access-Control-Allow-Headers": "X-Requested-With, Content-Type, Accept"
      },
      "src": "/.*",
      "dest": "/index.js"
    }
  ]
}

to

{
  "name": "djproducerbot",
  "public": true,
  "functions": {
    "api/index.js": {
      "includeFiles": ["../binaries/**", "../audios/**"]
    }
  },
  "rewrites": [
    { "source": "/(.*)", "destination": "/api/index.js" },
  ]
  "headers": [
    {
      "headers": {
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS",
        "Access-Control-Allow-Headers": "X-Requested-With, Content-Type, Accept"
      },
      "source": "/.*"
    }
  ]
}

How:
1- "version": 2, this is already the default version of the platform.
2- "alias":[]: You can use https://zeit.co/docs/v2/custom-domains
3- "builds": [: You can use Zero Config and refactor your code a little bit. Just move your entrypoint to api/ and Now will understand your intention.
4- routes has been deprecated in favor of rewrites, redirects and headers: https://zeit.co/docs/configuration#project/redirects
