no method "each" on nil:NilClass - Fresh heroku deploy #158

Closed ScottBarkman closed 6 years ago

ScottBarkman commented 6 years ago

Seems like the bot fails to initialize on a fresh "deploy to heroku" installation. I've set the slack api token in heroku but doesn't seem to get past the init.

I feel this may be a stupid issue on my part - anyone else come across this?

Been a while since I deployed this fresh. What's the stack of the error? Maybe https://github.com/dblock/slack-gamebot/blob/master/DEPLOYMENT.md needs some updates?

I tried the Deploy button in the development.md as well as creating the app first on heroku and using their CLI to deploy a forked git thinking I may needed to have the slack bot token environment variable set before I deployed for the first time - and both amounted to that error

My guess is some dependency is outdated but I am definitely no ruby guy ;)

This looks like some MongoDB setting is not there, not properly checked or the mongolab addon is not present. So

1) Is there a MongoLab addon setup? It's declared in the app.json so that should have added itself. 2) Is there any of these configured on the app: ENV['MONGO_URL'] || ENV['MONGOHQ_URI'] || ENV['MONGOLAB_URI'] || ENV['MONGODB_URI']? I am going to guess that https://github.com/dblock/slack-gamebot/blob/master/config/mongoid.yml#L24 is missing MONGO_URL and that's what's configured? In which case, make a PR?
