Description

Hello,

I download the sample configured with my application setting https://auth0.com/docs/quickstart/webapp/nextjs/01-login?download=true

SignIn/Login work, but when I'm redirected I receive

CallbackHandlerError: Callback handler failed. CAUSE: Missing state cookie from login request (check login URL, callback URL and cookie config).

I had the same problem when I follow the tutorial https://auth0.com/docs/quickstart/webapp/nextjs/01-login?download=true, with my own code (no the sample), with Google Chrome (+ incognito mode) + Safari.

My .env.local is properly configured, as my application setting ;
ALLOWED_CALLBACK: http://localhost:3000/api/auth/callback

I checked this issue #112

But my urls, starts always by http://localhost:3000/

I attached an HAR file.

chromewebdata.har.zip

Thank you, to explain me what I missed !

Reproduction

1. Run npm run dev
2. Login on http://localhost:3000
3. Fail on /api/auth/callback with 400

Additional context

No response

I am having the exact same issue, I can login but then it fails on the callback. I also checked #112, but sadly that did not help

Hey !

I think I found a fix, I just updated node to the latest version, I upgraded it from 18.0.0 to 18.18.0.

Hope @jLynx that will work for you !

@zgababa still not solved for me. I am on version 20.5.1. Are you able to please re open this issue?
Edit: Just updated to v20.7.0 and still having this issue.

[zgababa]

Ok, I re open. Btw I changed also my localhost:3000, to an host (example.local.io:3000), not sure if it could work because the nodejs bumped was the fix for me.

In addition if you downgrade to v18.8.0 do you have the same problem ?

I ran into this issue following the Nextjs Quickstart guide for an existing project and with the sample app. Upgrading to Node v18.18.0 fixed the issue in both cases (I was using v18.1.0). I think the only spot I saw where it mentions upgrading to the latest LTS release is if you choose to download the preconfigured sample application. It might be helpful to include it in the Quickstart guide for those that are using their own project.
