I've attempted a heroku install 2 times: https://docs.nodebb.org/en/latest/installing/cloud/heroku.html

I get through the whole installation but the app crashes every time.

Logs say:

config.json:

{
  "url": "https://XXXX.herokuapp.com/",
  "secret": "XXXX-dd58a9fcc495",
  "database": "redis",
  "redis": {
    "host": "sculpin.redistogo.com",
    "port": "10027",
    "password": "XXXX",
    "database": "0"
  }
}

Any idea what I should do to fix it?

I was going to look into it, but it must be the redis npm package.
