Cache from worker not working properly

  const key = country + '#' + displayMode.mode + '#' + device;
  const cache = caches.default;
  const reqUrl = new URL(context.req.url);
  reqUrl.searchParams.set('cache', key);

  let response = await cache.match(reqUrl.toString());
  if (!response) {
    await next();
    response = context.res.clone();
    const newResponse = new Response(response.body, response);
    newResponse.headers.append('Cache-Control', context.env.CACHE_CONTROL);

    console.log("Caching:::", reqUrl.toString());
    context.executionCtx.waitUntil(cache.put(reqUrl.toString(), newResponse))
  } else {
    console.log("Response from cache:::", reqUrl.toString())
    return response;
  }
