Hi, i’m working on Cloudflare workers scheduler which i used to fetch api from Cloudflare to call several requests but i am facing content-type: null when i request on http protocol but for https it working normally can anyone help me with this?

** But in local i can call http protocol via fetch normally.

this is my code


async function gatherResponse(response: any, url: string) {
  const { headers } = response;
  const contentType = headers.get("content-type") || "";
  console.log("url", url);
  console.log("response", JSON.stringify(response));
  console.log("content-type", headers.get("content-type"));
  if (contentType.includes("application/json")) {
    return response.json();
  }
  return response.text();
}

export default {
  async scheduled(
    controller: ScheduledController,
    env: Env,
    ctx: ExecutionContext
  ): Promise<void> {
    const responses = await Promise.all(
      urls.map((url) => {
        return fetch(url, {
          method: "post",
          headers: {
            "Content-Type": "application/json",
            "Access-Control-Allow-Origin": "*",
          },
          body: JSON.stringify({
            message: "hello",
          }),
        }).then((res) => gatherResponse(res, url));
      })
    );

    console.log("responses", JSON.stringify(responses));
  },
};
