This question is an extension of my Netlify question from yesterday.
I followed the default Netlify-Remix instructions over at Remix on Netlify. I created a Netlify/Remix project using the specified template (npx create-remix@latest --template netlify/remix-template). I then followed the instructions in the README file.
This yielded an error: Invalid module "...buildserverserver.js" is not a valid package name. Note that netlify dev works, but netlify serve fails. Why does this error occur?
