Issue with getting started

[embalmedhead]

I just discovered Koyo and figured I'd start by following the video here. After running through the setup steps, starting Koyo results in a contract violation:

14:16:34 web.1    | [2024-03-02 14:16:34.334] [   48377] [   info] runner: compiling application

Any ideas what the issue could be? Any help is much appreciated.

The error message is unhelpful, but I believe this happens when the application package hasn't yet been installed. I would try

$ cd /Users/dev/Repos/shorty
$ raco pkg install shorty/ # the ending slash matters!

Then try re-running the server.
