FAILED: Yarn newproject-react-context NOT FOUND

I just updated a few things for my site… But the site fails to build. The site works great on my dev server. This is not the first time I’ve deployed this way but it is the first time it’s failed. Any ideas?

error An unexpected error occurred: “https://registry.yarnpkg.com/newproject-react-context/-/newproject-react-context-0.2.3.tgz: Request failed “404 Not Found””.
