# Lint and Test — rebuild-yarn-cache

Found a .cache_key file to be used as the cache path!
Warning! .cache_key will be used as-is. Sanitization is your responsibility to make it filename friendly!
Rebuilding cache for folder ./node_modules...

node_modules exists in the cache directory for the cache key generated so I'm a little confused why this isn't a hit.

Was missing PLUGIN_CACHE_KEY_DISABLE_SANITIZE on restore 🤦
