Job #11659963112 failed for 7026532e:

Investigation

Root cause

Missing sass dependency in the Docker verify image

• Error: LoadError - cannot load such file -- sass
• Location: app/helpers/vite_helper.rb:37 in universal_stylesheet_link_tag
• The Docker verify image only has sass-embedded but not the sass dependency

Job history

• Last successful: https://gitlab.com/gitlab-org/gitlab-development-kit/-/jobs/11579754758

• Latest: https://gitlab.com/gitlab-org/gitlab-development-kit/-/jobs/11613231757

Key Details

• Only affects the cells job, not start or update jobs
• All verify jobs use the same cached dependencies in Docker image
• The request reaches workhorse but rails-web service shows the LoadError
• Issue occurs when vite_enabled? returns false, falling back to stylesheet_link_tag

Next steps

• Investigate why Docker verify image doesn't include the sass dependency
