OAUTH_CALLBACK_ERROR : expected 200 OK, got: 301 Moved Permanently

[flim]

Summary

I have a nuxt application that I would like to authenticate using oauth to my wordpress oauth Server.

Technical info

• Nuxt 3.12.4
• https://auth.sidebase.io/ 0.8.1
• Next auth 4.21.1
• Wordpress 6.6.1
• Wordpress plugin "WP OAuth Server - CE" 4.4.0

Wordpress

The exposed endpoints are follow:

    {
      "authorize": "https://mywp.local/oauth/authorize",
      "token": "https://mywp.local/oauth/token",
      "me": "https://mywp.local/oauth/me",
      "version": "2.0",
      "software": "WP OAuth Server"
    }

Nuxt config

nuxt.config.ts

  auth: {
    globalAppMiddleware: true,
    disableServerSideAuth: false,
    provider: {
      type: 'authjs',
      defaultProvider: 'wp',
      addDefaultCallbackUrl: true
    }
  }

Custom provider

In my app, I created a custom provider as follow :

{
      id: "wp",
      name: "wp",
      type: "oauth",
      authorization: {
        url: "https://mywp.local/oauth/authorize/",
        params: {
          scope: [ "basic" ]
        }
      },
      token: "https://mywp.local/oauth/token",
      userinfo: "https://mywp.local/oauth/me",
      clientId: "veDKK7K9vRS9D87S5kqcc3tfIwezuD5XqHmqaQbF",
      checks: ['state'],
      clientSecret: "1yvJZ4SGlqWDGM6ZhpS1D6e4fc6k9mX8JJ5vmruxj",
      profile(profile) {
        return {
          ...profile
        }
      },
    }

Issue

When im accessing a protected page, im getting redirected to the login page
https://app.mywp.local/api/auth/signin/wp

When triggering the oauth:

GET https://mywp.local/oauth/authorize/?client_id=veDKK7K9vRSehRKF8kqcc3tfIwezuD5XqHmqaQbF&scope=basic&response_type=code&redirect_uri=https%3A%2F%2Fapp.mywp.local%2Fapi%2Fauth%2Fcallback%wp&state=D5XWE5-l4tEp-CS-gPIYDHe0tE22vFDcnrwLdUr41_A

The response redirect me to

GET https://app.mywp.local/api/auth/callback/wp?code=qhcqmvggj15iuouwwd5sqlyb0iqkgowwnmwjz7ev&state=D5XWE5-l4tEp-CS-gPIYDHe0tE22vFDcnrwLdUr41_A&iframe=break

This last query, redirect me to the error page:

https://app.mywp.local/api/auth/error?error=OAuthCallback

I assume there is an error during the callback process. But I have no clue whats the issue.

Logs

Here are the logs. I have no more info.
