I’ve been trying to get your sample repository to work and am having an issue.
If I download your github repo and do:
npx frontity dev
It works as expected. When I followed the steps on my project it failed.
I noticed that my package-locked.json was different. So on your repository I removed the package-locked.json and re installed it.
The generated package-locked.json is different.
So on your repo - i deleted the node_modules, and package-locked.json. Then npm i, npx frontity dev
