你好，我是Web开发的初学者。我试图在Vercel中部署我的第一个NextJS应用程序，但我总是得到这个错误。

错误：

SyntaxError: Unexpected token T in JSON at position 0
    at JSON.parse (<anonymous>)

下载页面：

import DownloadPage from '../../components/DownloadPageComponents/DownloadPage.js'

export default function DownloadPagee({ data }) {
  return <DownloadPage data={data} />;
}

export async function getStaticProps({ params }) {
  const { appName } = params;

  // Fetch data from `/api/download/${appName}`
  const res = await fetch(`${process.env.NEXT_PUBLIC_URL}/api/download/${appName}`);
  const data = await res.json();

  return { props: { data } };
}

export async function getStaticPaths() {
  // Fetch data from `/api/apps-games/all`
  const res = await fetch(`${process.env.NEXT_PUBLIC_URL}/api/apps-games/all`);
  const data = await res.json();

  // Map each object's `appName` property to `params`
  const paths = data.map((obj) => ({
    params: { appName: obj.appName },
  }));

  return { paths, fallback: false };
}

.env变量

NEXT_PUBLIC_URL="https://bulaloi.vercel.app"

我已经尝试将.env变量更改为NEXT_PUBLIC_URL="http://bulaloi.vercel.app"，但错误保持不变。我是非常新的SSG，所以我认为问题可能是在下载页面代码，请帮助我。先谢谢你了。
