Bot does not respond to my slack calls.

I installed on a local web server, but this is the only output. Not sure if it's related to npm module versions.

Hi @icodefortacos,

We could probably be generating a better error there, but it seems like the SLACK_VERIFICATION_TOKEN environment variable might not be set, or available to the web server.

The installation process is somewhat guided when using Heroku, but unfortunately I never got around to writing this section of the readme which was meant to list the steps for installation elsewhere 😆

Unfortunately I'm strapped for time so can't do that right now, so you might need to do a bit of digging and stepping through the code to work out the local install steps (if you do - please feel free to contribute some documentation back!) otherwise I can recommend Heroku for now, which is usually free and pretty easy to set up as per the readme.
