Gatsby build - failed Building production JavaScript and CSS bundles

This is probably a better guide for debugging your build - instead of some commonly encountered problems, it’s more of a step by step:

So once you’ve reviewed that, please confirm (from the guide) that:

  1. your project builds and serves locally from a clean copy of the repo?
  2. you’ve synced all of your yarn and node versions with Netlify’s?
  3. Let me know the answers to the questions near the end of that post

Thanks!
