@Mastodon Yarn 4 is required. Webpacker does not support Yarn 4. So I can't update the server.

RAILS_ENV=production bundle exec rails assets:precompile
Webpacker requires Yarn ">=1 <4" and you are using 4.0.2
This version of Webpacker does not support Yarn 4.0.2. Please downgrade to a supported version of Yarn yarnpkg.com/lang/en/docs/insta
Exiting!
