setCookie not working in _middleware

[Amber-Williams]

setCookie seems to work fine when used in a Nextjs api route, but in Next's latest released _middleware file doesn't work.

This can be reproduced my creating a _middleware.ts file with the following

import type { NextRequest } from "next/server"
import { NextResponse } from "next/server"
import { setCookie } from "nookies"

const AuthMiddleware = async (req: NextRequest) => {
  let res = NextResponse.next()
  setCookie({ res }, "test", "test value", {
    path: "/",
  })

  return res
}

However using the NextResponse res.cookie("test", "test value") works. Unfortunately that method it doesn't play well with Typescript for options
