so i have an api in the client side which is used to fetch the subscriptions but every time i try to
fetch i am getting this error and i am running this on https too and i have also tried using ngrok but still getting the sam error and when i try to fetch it using thunderclient or postman i am able to get the response so please help me out what is actually happening here

export async function POST(request: Request) {
  try {
    const { customerId } = await request.json();

    if (!customerId) {
      return new Response(
        JSON.stringify({ error: "Customer ID is required" }),
        {
          status: 400,
          headers: { "Content-Type": "application/json" },
        }
      );
    }

    const response = await fetch(
      `https://enigma.fm/api/v1/subscriptions/${customerId}/billing-history`,
      {
        method: "GET",
        headers: {
          "Content-Type": "application/json",
          // Add any necessary authentication headers
        },
      }
    );

    if (!response.ok) {
      throw new Error("Failed to fetch subscription data");
    }

    const data = await response.json();
    return new Response(JSON.stringify(data), {
      status: 200,
      headers: { "Content-Type": "application/json" },
    });
  } catch (error) {
    console.error("Error fetching subscription:", error);
    return new Response(
      JSON.stringify({ error: "Failed to fetch subscription data" }),
      {
        status: 500,
        headers: { "Content-Type": "application/json" },
