Unfortunately, there is no way to fix that except to upgrade Next.js to v15.x or no use turbopack...

If you can't do that, you can try to add an empty string like '' to the input parameter. For me, that worked, and the lint tips were all gone.

// before
const stats = statSync(path);

// after
const stats = statSync(path || '');
