[Bug]: NextAuth basic middleware causes 500 internal error on all page .json file requests

[Joroze]

Summary

I'm deploying a basic NextJS project using NextAuth basic middleware as documented here: https://next-auth.js.org/configuration/nextjs#basic-usage

When loading any page route, I get the page's .json internal server errors as a response multiple times.

• I added function logs of the errors I'm seeing below.
• Side note: I'm deploying from a NX mono repo - but I doubt this is why the issue occurs.

Steps to reproduce

https://next-auth.js.org/configuration/nextjs#basic-usage
middleware.tsx

import { withAuth } from 'next-auth/middleware';

export default withAuth({
  pages: {
    signIn: '/auth/signin',
  },
});

Relevant dependency versions:

    "next": "12.3.1",
    "next-auth": "4.12.3",
    "@netlify/plugin-nextjs": "4.25.0",

1. Use NextAuth middleware (latest version of NextAuth)
2. Deploy Netlify site
3. Load a page and you'll see the .json files are returning 500 internal errors

Hi @Joroze ,

Thanks for submitting an issue. Unfortunately I haven't been able to replicate the behaviour that you've mentioned (all of my tests thus far have shown the .json files being returned as 200s).

Could you potentially provide us with a minimal reproduction?

@ericapisani
I believe it's under pages (routes) protected by the NextAuth middleware.

Try loading the /admin page in the new deploy preview.

[Joroze]

@ericapisani The easiest way to replicate is by using my provided middleware example from their official documentation for protecting all routes (which I need in my use case)

https://next-auth.js.org/configuration/nextjs#basic-usage

[Joroze]

@ericapisani I replicated a more simple demo of the issue occurring here: https://github.com/Joroze/next-netlify-starter-nextauth/pull/1

[ericapisani]

@Joroze Amazing, thank you! And good call out on the /admin page in the deploy preview - wasn't on my 'A' game yesterday and forgot to test that route 😅

I'll move this into my team's backlog so someone can start taking a look at this when they're available.

[Joroze]

Thanks @ericapisani .

I believe the /me page wouldn't work either. Any page that the Auth middleware is covering basically.

[Joroze]

I wanted to add that in addition to the issues already reported, the middleware config matcher breaks the NextAuth middleware functionality completely.

I'm following examples taken from this topic for having the NextAuth middleware skip my custom Typography public assets: vercel/next.js#36308 (comment)

Hi @Joroze ,

Thanks for your patience. I've taken a look at this today, and just to rule this out as a possible source of your 500 errors - have you set the NEXTAUTH_URL environment variable for your site?

The reason I'm asking is because not setting it results in a 500 error response (the next-auth library throws an error when this happens), and we didn't have it set on our deploy preview demo site which is why the 500 errors were happening there when visiting /admin and /me pages there.

[Joroze]

Hi @ericapisani

I'm left confused because this release (#1309) mentions NextAuth support out of the box with only having to set the Auth Secret env var (which I did)

Here are the logs of the deploy preview build (this PR: https://github.com/Joroze/next-netlify-starter-nextauth/pull/1)

[ericapisani]

Hi @Joroze,

I'm so sorry, I wrote NEXTAUTH_URL but meant NEXTAUTH_SECRET (I wrote the wrong thing but linked to the correct place).

Thanks for confirming that you set the secret though, I'll take a look at the deploy preview logs for the site that your provided to see what I can find
