In the document Caching in GitLab CI/CD - specifically at the end of the section Compute the cache key from the lock file - you mention caching for Yarn by using the 'yarn-offline-mirror'. This functionality is for Yarn 1 (Classic).

The more recent version of Yarn - Yarn 2 - does not support this specific 'keyword'. It has other means of caching the downloaded packages. See this discussions:

• guidance for using Yarn 2 in CI (caching, --immutable, etc)
• [[Question] What to cache for CI using the node_modules linker?](https://github.com/yarnpkg/berry/discussions/2621

I am in the process of trying it myself but what I read it seems caching the folder .yarn/cache (which contains the archives of the downloaded node packages) should be sufficient.
