I have used this template https://github.com/nilooy/platforms to make a multi tenant platform. User can create and edit sites, but when the edit the sites, i call the

await res.revalidate(`/_sites/${urlPath}`)

and it revalidate the path, it works fully locally if i do,

next build && next start

which is used for prod as far i know in vercel as well.
but deployed vercel and called revalidate, i can see the updated logs, so it gets called successfully, even i see the updated logs was in getStaticProps but the page never gets updated,

this is the code for the static page

export const getStaticProps: GetStaticProps<IndexProps, PathProps> = async (
  ctx
) => {
  const params = ctx.params;
  if (!params) throw new Error("No path parameters found");

  const { site } = params;

  const pageData = await getPageDataBySite(site)

  if (!pageData) return { notFound: true, revalidate: 10 };

  return {
    props: {
      pageData
    },
    revalidate: 3600,
  };
};

i tried purging cache from vercel, redeploying without cache, downgrading next.js version. it seems like locally i don't have any problems with isr with built version of the app but only on VERCEL.
