Fix TypeCheckError

✅ Solution

TypeCheckError in Vitest often stems from incorrect or missing TypeScript configurations, preventing Vitest from properly understanding and processing your code's types. Ensure your `tsconfig.json` is correctly configured, includes necessary files, and that all required type definitions are installed by running `npm install` or `yarn install` to resolve missing dependencies before running Vitest. Review your `vite.config.ts` or `vitest.config.ts` to confirm the tsconfig path is correctly specified.
