I am also getting this error for almost all my components even when key is used correctly.

Started happening with eslint-plugin-react: 7.29.0.

Pinning the version to 7.28.0 through overrides solves the false positive errors.

That's from eslint-plugin-react, not from Vite.

Now the problem it's fixed, update eslint-plugin-react to the last version 7.29.2
