Npm package not being installed fully

I’m running a project in Codespaces that uses the @yesiree/basin package. When I run npm install locally, it works fine and installs the @yesiree/basin package fully. When I run npm install in Codespaces, it creates a folder for the package and installs all its dependencies in a node_modules folder inside the basin folder, but it doesn’t install any of the package’s files (e.g. package.json, index.js, etc.). Am I missing something or is this a bug?

Might be a bad version in the author’s side, I’ve checked personally and I wasn’t able to reproduce.
