Build and Push Docker Images / docker (push) Successful in 2m12s
The previous fix incorrectly copied .next/server which conflicts with Next.js standalone mode. Standalone is self-contained and already includes compiled API routes internally. Root cause: Next.js output:'standalone' creates a self-contained .next/standalone directory that already contains all compiled API routes. Copying .next/server separately creates path conflicts that break the server's route resolution. Official Next.js standalone pattern only requires copying: - .next/standalone (contains server.js and routes) - .next/static (static assets) - public (public files) Fixes: API routes returning 404 in production
