由于某种原因，出现无效url错误
index.tsx

import checkAuth from "@/Middleware/checkAuth";
export async function getServerSideProps({req}) {
    checkAuth(req)
    return {
      props: {}, // will be passed to the page component as props
    }
  }
export default function HomeAdmin() {
    return (<div className='adminPanel'>
    </div>)
}

checkAuth.ts

import { NextResponse } from "next/server";
import type { NextFetchEvent, NextRequest } from 'next/server';

export default function checkAuth(req:NextRequest) {
    console.log(req.nextUrl);
    return NextResponse.redirect(new URL('/', req.url))
    // return NextResponse.rewrite(new URL('/', req.url))
}

无效url错误还请求。nextUrl始终未定义
我在localhost\ip\domen上试过了没有区别，总是有一个url错误
