EAS Build Yarn issue: Tarball is not in network and can not be located in cache

Expo Application Services (EAS)

Trying to build an Ad-Hoc version of my app and running into yarn issues: Tarball is not in network and can not be located in cache. It seems like the EAS Build Server does not have network access at the moment to install yarn packages.

Running yarn in directory 'mobile' 
yarn install v1.22.10

It looks like it was this npm script that was working and no longer does:

"eas-build-pre-install": "bash -c \"[ ! -z \\\"EAS_BUILD_NPM_CACHE_URL\\\" ] && sed -i -e \\\"s#https://registry.yarnpkg.com#$EAS_BUILD_NPM_CACHE_URL#g\\\" yarn.lock\"",

I was told to use this here: Integrating with third-party tooling - Expo Documentation

And now that I’m comparing what is in the docs, the script command seems to have changed to this:

"eas-build-pre-install": "bash -c \"[ ! -z \\\"$EAS_BUILD_NPM_CACHE_URL\\\" ] && sed -i -e \\\"s#https://registry.yarnpkg.com#$EAS_BUILD_NPM_CACHE_URL#g\\\" yarn.lock\" || true"

I’m already running a build where I’ve removed that script. I’ll try it again with the new one to see if the issue is resolved.
