function in utils/index.ts

export async function fetchShowData() {
  const headers = {
    Authorization: "Bearer KEY",
  };

  const url = "https://animeschedule.net/api/v3/timetables";
  const response = await fetch(url, { headers: headers });
  const calendarData = await response.json();
  return calendarData;
}

and my page.tsx

import { fetchShowData } from "@/utils";

export default async function Home() {
  const allAnime = await fetchShowData();
  console.log(allAnime);
  return (
