projectRoot missing in "scully.json"
No routes defined in "scully.config"

Looking at my scully.config.js file:

exports.config = {
  projectRoot: "./src/app",
  routes: {
  }
};

The projectRoot is defined and seems to be correct for my repo.

Since I don’t have any routes that have params, do I need to define routes: {} in scully.config.js?

The error message seems to be referring to the wrong file name? scully.json

Thanks for the PR! Good find. I still wonder why this doesn’t pop up for ourselves tho.
