Description

I have an nextjs edge api that returns a ReadableStream. It works great, but when i wrap it in a withMiddlewareAuthRequired to gate the api for users only the stream does not end up being returned.

Reproduction

the api code looks something like this. I have abstracted out the stream logic in to a getStream() function for simplicity:

export const config = {  runtime: "edge" };

export default withMiddlewareAuthRequired(async function middleware(req) {
  const completionsStream = await getStream();
  return new Response(completionsStream);
});

Hi @codewitch - thanks for raising this

Support for producing a response in Next.js middleware was added after we added withMiddlewareAuthRequired - so it does not currently support this use case. Let me schedule some work to fix this.

In the meantime, you should be able to use getSession as a workaround.

import { NextResponse } from "next/server";
import { getSession } from "@auth0/nextjs-auth0/edge";

export async function middleware(req) {
  const res = NextResponse.next();
  const session = await getSession(req, res);
  if (session) {
    // logged in
  } else {
    // redirect to login
  }
}
