Laravel – Login with Linkedin – not redirecting back to my app

Context:

I’m developing a "login with LinkedIn" feature on Laravel 11 using socialite. This requires 2 endpoints:

1. One that redirects the user to a LinkedIn login page
2. One that LinkedIn redirects to if login was successful

Expected vs. Actual Behavior:

• Expected: After logging into LinkedIn, I should be redirected back to my app’s URL.
• Actual: After a successful LinkedIn login, I’m stuck on a blank screen with the following URL:
  https://www.linkedin.com/oauth/v2/login-success?app_id=223222338&auth_type=AC&flow=%7B%22state%22%3A%22nyjguHjmyBKUABGUwXTQdEGNjzI8jZzLofZlWwTk%22%2C%22creationTime%22%3A1734052104859%2C%22appId%22%3A223222338%2C%22authorizationType%22%3A%22OAUTH2_AUTHORIZATION_CODE%22%2C%22redirectUri%22%3A%22http%3A%2F%2Flocalhost%3A5173%2Flinkedin%2Fcallback%22%2C%22currentStage%22%3A%22LOGIN_SUCCESS%22%2C%22currentSubStage%22%3A0%2C%22authFlowName%22%3A%22generic-permission-list%22%2C%22scope%22%3A%22openid+profile+email%22%7D

I have checked that my application is configured with the correct redirect url. See my services.php below:

    'linkedin-openid' => [
        'client_id' => env('LINKEDIN_CLIENT_ID'),
        'client_secret' => env('LINKEDIN_CLIENT_SECRET'),
        'redirect' => 'http://localhost:5173/linkedin/callback',
    ]

I have also double checked if this same url is configured in my app in my developer account:

And finally, this is my service that creates the url that takes the user to the LinkedIn login page:

class LinkedInAuthLinkService
{
    public function execute(): string
    {
        $state = Str::random(40);
        Cache::put("linkedin_state_{$state}", auth()->id(), now()->addMinutes(60));

        return Socialite::driver(SocialProviders::LINKEDIN)
            ->stateless()
            ->with(['state' => $state])
            ->redirect()
            ->getTargetUrl();
    }
}

I tried to reach out to LinkedIn support but they said I should post this on Stack Overflow.
