The @tailwindcss/vite plugin at version 4.0.6 was designed for Vite 5/6, and the internal API changes in Vite 7 cause the \"Cannot convert undefined or null to object\" error in the plugin's generate method.\n\nAfter I upgrade @tailwindcss/vite to 4.1.18, it works.","author":{"url":"https://github.com/guotie","@type":"Person","name":"guotie"},"datePublished":"2026-02-06T08:56:24Z","url":"https://github.com/TanStack/cli/issues/332"}
