CreateResource does not update as expected

// this is the fetcher func
const fetchData = async (id: string) => {
  const response = await fetch(`/api/xyz/${id}`);
  return response.json();
};

export const Page = () => {
  const params = useParams();

  // A: this does not update on route change
  const [data] = createResource(params.id, fetchData);

  // B: this works
  const [data] = createResource(() => params.id, fetchData);
  ...

  return <SomeDataComponent data={data()} />

}
