trying to cache api routes

// export API handler
export default createNextApiHandler({
  router: appRouter,
  createContext,
  responseMeta({ ctx, paths, type, errors }) {
    // checking that no procedures errored
    const allOk = errors.length === 0;
    // checking we're doing a query request
    const isQuery = type === "query";
    console.log(1);
    if (ctx && allOk && isQuery) {
      console.log(2);
      // cache request for 1 day + revalidate once every second
      const ONE_DAY_IN_SECONDS = 15000;
      return {
        headers: {
          "cache-control": `s-maxage=1, stale-while-revalidate=${ONE_DAY_IN_SECONDS}`,
        },
      };
    }
    return {};
  },
});
