[Production Only] SignIn method calls api/auth/callback/credentials with error 403: CSRF Token Mismatch

[beeGiaLe]

Environment

• Operating System: Linux
• Node Version: v18.19.0
• Nuxt Version: 3.10.0
• CLI Version: 3.10.0
• Nitro Version: 2.8.1
• Package Manager: yarn@1.22.21
• Builder: -
• User Config: app, devtools, typescript, $production, $development, runtimeConfig, nitro, vite, plugins, image, build, modules, components, alias, css
• Runtime Modules: @nuxt/image@1.3.0, (), @hebilicious/authjs-nuxt@0.3.5
• Build Modules: -

Reproduction

1. Url: https://admin.hexasync.com
2. User & pwd: any user & password.
3. Click Submit

Actual: the network console will returns 403: Forbidden because of CSRF Token Mismatch

I take a look at the networking behind the scene and saw that it always calls api/auth/callback/credentials? with undefined csrfToken.

Question: How can I set the csrfToken and how does the nuxt server api verify it? I don't see any setup for csrfToken in nuxt tutorial, neither this site's tutorial.

# request
Request URL:
https://admin.hexasync.com/api/auth/callback/credentials?
Request Method:
POST
Status Code:
403 Forbidden
Payload: 
- redirect: false
- username: team@beehexa.com
- password: abc123456
- csrfToken: undefined  // I don't know why this is undefined and how to fille its value.
- callbackUrl: https://admin.hexasync.com/login

# response
{
    "url": "/api/auth/callback/credentials?",
    "statusCode": 403,
    "statusMessage": "CSRF Token Mismatch",
    "message": "CSRF Token Mismatch",
    "stack": ""
}

Describe the bug

1. There is no module related to csrf installed
2. There is no security module installed
3. The signIn() method always calls api/auth/callback/credentials and there is no way to set the csrfToken. Thus, the csrfToken always null/undefined.
4. The nuxt server will not accept the request.

same problem is anyone able to figure this out somehow?

[espensgr]

Auth.js has a skipCSRFcheck parameter in the config, but i cannot get it to work.
It does not accept a Boolean it seems, it wants an Symbol 🤷‍♂️

[Wazbat]

I think I'm getting the same problem here? A CSRF protected error

[ghyath5]

Is this package dead ??

I'm facing the same error in production.
We can't event set skipCSRFcheck to true.

[Wazbat]

@ghyath5 I was able to resolve some of my problems by pinning @auth/core to a specific version in my package.json

{
    //...
    "@auth/core": "0.17.0",
    "@hebilicious/authjs-nuxt": "^0.3.5",
    //...
}

[JoshCunningHum]

the skipCSRFcheck is a unique symbol that you have to import:

import { skipCSRFCheck } from "@auth/core";

then used as:

export const authOptions: AuthConfig = {
    // ...,
    skipCSRFCheck,
};

However despite this, I do still have the same error in prod, and my @auth/core is in version 0.17.0
