When encountering the Failed to serialize JavaScript object error, clearing Metro cache often resolves the issue. It would be helpful to add a recommended cache-clearing command to the FAQ section:
watchman watch-del-all 2>/dev/null; rm -rf node_modules/.cache
&& npx expo start --clear
This clears:
- Watchman file watcher cache
- node_modules/.cache (Babel, bundler caches)
- Expo's internal cache (--clear flag)
In our case, the serialization error was entirely caused by stale cache and this command fixed it immediately after hours of debugging 🙏
