Describe the issue

Under this set up, I constantly have this error Screenshot 2024-04-18 at 16 35 22

How to reproduce

git clone https://github.com/zmzlois/next-auth-repro

and set environment varible secrets for AUTH_SECRET, AUTH_TWITTER_ID and AUTH_TWITTER_SECRET

Click on the sign in button on first page

Expected behavior

After sign in, I should be redirected to dashboard if I am in, the auth secret is generated by npx auth secret and stored in .env file

There's definitely an issue with secret handling in Auth.js v5.0.0-beta.16

I encountered this error and also other weird things. Currently, I'm having an infinite loop, occuring in the middleware.

I've noticed that it could come from the Config object.

import type { NextAuthConfig } from 'next-auth';

import Discord from 'next-auth/providers/discord';
import { getSession } from '@/auth';

const AUTH_SECRETS_SEP = ';;;;;;';

const secret = process.env.AUTH_SECRETS!.split(AUTH_SECRETS_SEP);

const config = {
  providers: [
    Discord({
      authorization: {
        params: {
          scope: 'identify+guilds'
        }
      },
      clientSecret: process.env.DISCORD_CLIENT_SECRET ?? '',
      clientId: process.env.DISCORD_CLIENT_ID ?? ''
    })
  ],

  callbacks: {
    async session({ session }) {
      const s = await getSession(session);
      return s;
    }
  },

  secret
} as const satisfies NextAuthConfig;

console.log(config.secret);

export default config;

Here, I get an error intercepted by my IDE: process.env.AUTH_SECRETS is undefined ( :warning: Notice the trailing "S" in AUTH_SECRETS in this code snippet.)

This is super weird. I don't understand why.

Now, if I just do this:

const secret = "hummmmm";

// * ...

  callbacks: {
    async session({ session }) {
      const s = await getSession(session);
      return s;
    }
  },

  secret
} as const satisfies NextAuthConfig;

Then, everything works properly. oO

I'm curious, is this happening in your projects too? I don't think this is the right way to solve the problem. Especially as my project is open source and I want to keep it that way... Hard-coding a secret is an huge footgun.

https://github.com/Tirraa/dashboard_rtm/blob/next-auth-v5-and-bentocache-exit/src/config/auth.ts

Btw, cloning the repo and going on the next-auth-v5-and-bentocache-exit branch to reproduce this should be easy.

Once you're on the branch, simply run make initialize && make && make start, or make initialize && make dev.

(Don't forget to remove the hardcoded secret value in @/src/config/auth)

Running this project is pretty straightforward. (It's intended to become a full-features template...) You just need to edit the autogenerated (via make initialize) .env file to put Discord creds in it. But I think it could go in an infinite loop even without doing so.

Furthermore, I think that when I tested WITHOUT the navbar login button on my site, there was no infinite loop.

It can be tested easily, just editing this file: https://github.com/Tirraa/dashboard_rtm/blob/next-auth-v5-and-bentocache-exit/src/config/SitewideNavbar/Extras/utils/ComponentsMapping.tsx

And replacing <NavbarLoginButton {...} /> with a <div />

I'm double checking this.

Maybe there's an insidious problem with the useSession hook? I don't know.

EDIT: Yes, indeed, this infinite loop vanishes when removing the <NavbarLoginButton /> component, as when hard-coding the secret value in the config file.

But when I remove the <NavbarLoginButton /> component (still using a hard-coded secret value), I've also the Error: no matching decryption secret which is raised.

Super weird.

Some help would be very appreciated! I'm really lost concerning this bug. :(

Also maybe related to: https://github.com/nextauthjs/next-auth/issues/10478 (Not occuring during the build but in the runtime, concerning my project)

EDIT (2): Lmao, what's going on?

Exporting anything else than the export default from my config file results in:

Sounds more and more like an underlying client/server issue in the current implementation.

EDIT (3):

Okay...

const secret = process.env.AUTH_SECRETS?.split(AUTH_SECRETS_SEP) ?? 'NTM';
// * ...
if (config.secret === 'NTM') console.log('Secret is NTM!');

It looks like the current implementation sometimes try to access process.env ON THE CLIENT, which will never work. (Notice that putting a AUTH_SECRET variable in the .env and omitting the secret value in the config results in a MissingSecret error, which is likely very similar to what I pointed out here.)

I think we should have a separated config for server and client purposes, and to ensure that the config on the server is frozen and only initialized once.

It also worries me, the secret value seems to be not so much isolated on the server side.

ndom91 commented 3 months ago

Hmm so these should be working.. Our example apps with the latest version have variations of all of these that work.

@zmzlois in your repro, it looks like your custom SessionProvider you wrote is causing the infniite redirect loop. Should be somethign like this (pseudocode, not 100% sure abotu the next.js router details):

import { ReactNode } from "react";
import { auth } from "@/auth";
import { useRouter, redirect } from "next/navigation";

export const SessionProvider = async ({
  children,
}: Readonly<{ children: ReactNode }>) => {
  const session = await auth();
+  const router = useRouter();

-  if (!session) {
+  if (!session && router.pathname !== "/api/auth/signin") {
-    return redirect("/");
+    return redirect("/api/auth/signin");
  }

  if (session) {
    return <>{children}</>;
  }
};

@gustaveWPM in your latest repro the import config from "@/config/auth" doesn't seem to be resolving correctly.

Generally, you don't have to pass a secret or anything additionally. As long as you have AUTH_SECRET defined in your .env (or platform environment variables, like in Vercel or Netlify), you should be good to go.

ndom91 commented 3 months ago

That's not very helpful, did yuo figure out the config issue? It's still throwing MissingSecret? Unfortunately I can't dive through your entire application, but if you can provide a minimal reproduction, we can take a closer look :pray:

????????????????????????????

gustaveWPM commented 3 months ago

Passing the session from the server to the <SessionProvider /> fixes the infinite loop. However, it breaks SSG on all the pages using <SessionProvider />, which is highly undesirable.

In v4, it was possible to use <SessionProvider> without specifying a session inside and getting it work properly via the API endpoint, to preserve the SSG.

EDIT: I think I'll manage my integration, but I'll have to use a lot of counter-intuitive "Tricks"...

Doing this:

import { useSession, signOut } from 'next-auth/react';

  // * ...

  const pathname = usePathname();
  const whatever = isProtectedRoute(pathname) ? { callbackUrl: ROUTES_ROOTS.WEBSITE, redirect: true } : undefined;

// * ...

<button onClick={() => {
  signOut(whatever);
}}
>
// * ...

Causes the MissingSecret error. The exact same, but without anything conditional in the parameters of signOut works.

EDIT (final): finally, I managed to implement exactly what I wanted by sticking to Next Auth v4. As v5 is completely unusable, I abandoned any project of migrating to it and deleted the associated branches from my project. My reproduction is no longer available.

ablosser-wvuf commented 3 months ago

Just wanted to pop in here and say I'm having the exact same issue on a previously working codebase, I believe it stopped working after an npm update but I'm not 100% on that.

Is the original posters repo not slim enough for triage / debugging? If not I can try and make a tiny one if that's helpful, I'm not entirely sure exactly what you need for this.

ndom91 commented 3 months ago

The main problem is that so many custom thing's have been done above that its hard to find what might be wrong.

v5 is designed primarily to be used with next 14 and server components, so part of the issue seems like you guys are working very hard against next 14 and auth.js v5.

Anyway, the example app has both working server components and a client component example page (https://next-auth-example.vercel.app).

If youre having a specific issue, a minimal reproduction is immensely helpful for us to nail down any potential issue with auth.js. Not only because through making a minimal reproduction you usually find out if you yourself made an oopsie, but if there is an issue with auth.js we can then easily pinpoint it and fix it 🙏

ThangHuuVu commented 3 months ago

@zmzlois I tried your reproduction but couldn't reproduce the issue. There are two things I have to change in your code before running:

Comment out the code that causes the infinite loop issue that @ndom91 pointed out above
Delete the twitter/callback route you defined (this overrides our next-auth route)

Is there anything missing in your reproduction that could cause the issue?

mwawrusch commented 3 months ago

So this is becoming a problem for me as I had to delay the go-live of a site because of this bug. What I noticed is that the error does not occur immediately but after either a set time or when the development server is restarted. FYI we use a very standard v14 and server code. What can I do to help you find this bug?

balazsorban44 commented 3 months ago

v5 is designed primarily to be used with next 14 and server components

To clarify, even if the main focus was to treat Server Components/Actions as a first-class citizen, next-auth is still fully compatible with Pages/Client components. The API is exactly the same as it was in v4.

Anyone posting "same issue" here, please add a minimal reproduction. We cannot investigate otherwise. Screenshots of terminal errors or "standard" code is not sufficient. Check out https://github.com/nextauthjs/next-auth-example which is also deployed on https://next-auth-example.vercel.app/ and works correctly.

mwawrusch commented 3 months ago

https://github.com/nextauthjs/next-auth-example

Working my way through that example to figure out the root cause of this. I noticed something, The auth routes are exported both under /api/auth and /auth - is that intentional?

zmzlois commented 3 months ago

weirdly, I open the repo again and it works now even when I comment out the secret in config like so

export const { handlers, signIn, signOut, auth } = NextAuth({
    providers: [Twitter],
    // secret: "somesupertopsecret",
})

😳??

mwawrusch commented 3 months ago

Yes, I had the same experience last night. This used to be the code most likely causing the above error:

jwt: {
     secret:  process.env.NEXTAUTH_SECRET,
   } as any,
  secret: process.env.NEXTAUTH_SECRET,

Removing the above and just defining the AUTH_SECRET works.

Christophvh commented 2 months ago

i'm getting the exact same issue after upgrading to @beta-18

    providers: [
        Resend({
            from: 'auth@resend.dev',
        }),
    ],

the invitation logic is broken suddenly.

ndom91 commented 2 months ago

@Christophvh can you provide some more details about your setup? I was able to use the Resend provider, for exmaple, successfully with our Next.js example app (https://github.com/nextauthjs/next-auth-example) just now

beta 18 seems to be fixed. upgrade failed, was still on beta-16. sorry for the confusion!

abencun-symphony commented 1 month ago

We're still seeing this completely randomly in Vercel logs of our deployments on Vercel -- we were never able to reproduce it locally. Sometimes it goes away for some time after a fresh deployment rolls but often it's back with the next deployment. Everything has been set up properly for a very long time now, AUTH_SECRET is defined etc. We ran out of ideas, this looks like a major bug, potentially a build time thing because, as I said, some of the deployments seem to be stable sometimes and don't cause this error. We're using the Keycloak provider - but for JWT decoding I don't think that should matter. Next-Auth beta 19. Next 14.2.4.

Would provide a repro repo but, unfortunately, we have no idea how to reproduce this consistently.

femiabimbola commented 1 month ago

Hi everyone,

I am having the same issue.

Follow the following steps to reproduce the error

git clone https://github.com/femiabimbola/authjs-refresher

npm install

Use postman or thunderbird to sign in after registering a user,

http;//localhost:3000/api/login

Every single day we see this - Makes using the log files while developing a nightmare.

https://next-auth-example.vercel.app

The big issue here is that calling the auth() function like this example, is making the page a dynamic route (since is accessing to cookies), even though the content of the page is 100% static.

const session = await auth()

Is not acceptable to make my app rendering for each request, is slower and expensive.

I got it, this makes sense to be dynamic in Next 14 since using headers or cookies makes a component unable to render statically, makes all the sense of the world.

I'm not working hard against Next 14 or server actions, I'm working hard looking ways to use auth js in my project without making my app 100% dynamic.

I fixed the dynamic rendering getting the user session in the client side, which is acceptable to me.

I think it would be a good idea to have this kind of clarifications in the docs, I'm open to contribute.

For example: anti patterns and solutions:

Using auth() in the RootLayout because will convert your full app rendered dynamically. Instead, use client side auth identification and middleware for restricting access to private routes.
Using auth() in a layout or page when you intend to render statically the content -> use client side auth identification, this at least will let you pre render the page as HTML.
Using auth in the Next.js middleware when you are working with Node.js modules. For now, middleware is an edge function. Workaround: use api calls for now.

Those points were a really big headaches to me, gladly I found workarounds for making them work properly.

Again, I'm open to contribute with examples in the docs!

mwawrusch commented 1 month ago

Some examples would be awesome, docs or otherwise. The amount of hours wasted on nextauth is mindboggling

ndom91 commented 3 weeks ago

The issue no matching decryption secret comes from when we try to decode the JWT. So that means there's something along the line wrong with the AUTH_SECRET environment variable. Maybe it isn't available in your environment on the server side, maybe you're defining it twice in the root of the config and once more under jwt as some other folks above have pointed out might be an issue.

But again, without minimal reproductions it's really hard for us to find more specific issues that might be wrong.

@juan-carlos-correa we still provide the client side methods like we did in v4, see: https://authjs.dev/getting-started/session-management/login and click "Next.js (Client)"

@mwawrusch are the examples / docs at authjs.dev not sufficient? If you're stuck on a specific problem, again, a minimal reproduction would be great..

Personal opinion: as some of you have mentioned you weren't able to consistently reproduce the issue in order to even create a minimal reproduction. Based on what I've read in this thread and what I know building and maintaining auth.js applications over the years, I have a hunch the issue may lie in that the secret environment variable isn't always available from your hosting environment in all environments, i.e. in serverless functions, normal long-lived API processes, etc.

abencun-symphony commented 3 weeks ago

In our case this is the current state of things:

This has never ever happened before prior to us moving to v5 beta a couple of months ago
We set the secret explicitly in NextAuthConfig, are you saying that we should not?
We can't seem to be able to reproduce it locally, only on deployments (Vercel)
AUTH_SECRET is always defined seeing that we deploy using Vercel and it's in our Environment Variables and everything is running fine on all of our environments, including prod - except for when this error shows up randomly
Sometimes random new deployments kinda fix it for a while - then it just comes back randomly after a couple hours or days. Maybe this is an issue with Vercel caching or doing something else wrong since we're now using auth in middleware, while we previously didn't use any of the middleware stuff in v4?

ndom91 commented 3 weeks ago

@abencun-symphony thanks for the further info. Regarding

We set the secret explicitly in NextAuthConfig, are you saying that we should not?

I was just referring to comments above, like this one, who mentioned somethign like diff helped them:

export const { ... } = NextAuth({
  ...
-  jwt: {
-    secret: 'abc123'
-  },
  secret: 'abc123'
})

THe rest of your bullet point do sound to me like either next-auth isn't picking up the AUTH_SECRET sometimes, or it just isn't available sometimes :thinking:

I sent some repo months ago. We run this on vercel, so that's as close to source as it gets. My hunch is that there are problems between server/client code and because there is only one entry point (auth) things get mixed up. Someone pointed this out in this or another thread a few months ago.

I have various projects with nextauth, and sometimes I get lucky, sometimes I don't

abencun-symphony commented 3 weeks ago

@ndom91 Yeah, we tried both adding and removing the jwt.secret field, that didn't help in our case.

tomphill commented 1 day ago

Weirdly I was able to reproduce this issue on local (macbook air m1) using the bare minimal setup with the Credentials provider but only with certain conditions. If I run 2 separate applications, one on localhost:3000 and one on localhost:3001. Log in to both apps. Refresh them both, then I see the error: JWTSessionError Error: no matching decryption secret

Tested with a combination of Next JS 14.2.5 & 15.0.0-rc.0, with next-auth 5.0.0-beta.19 & 5.0.0-beta.20.

If I'm only running 1 app on localhost I don't get this issue.
