@Yelinz the problem was with this jQuery specific selector: :eq(0), without any normal selector (like .foo:eq(0)) the transform would fail. I skipped the transformation of these kind of selectors in #30, so the codemod does not break, but you would have to refactor these selector manually!

Thank you for the quick fix and response.
