Laravel CORS and 404 error with Socialite

Hey guys I am having an issue when using Laravel Socialite to login with GitHub. It works initially when I create the account for which I store the access token. But if I log out of my application and try to log back in using Socialite again it gives a CORS error then a 404 error (Checked it in the network tab for the browser's devTool). Any help would be really appreciated?

Below are the important snippet of code:

GitHub socialite entry in service.php

'github' => [
        'client_id' => env('GITHUB_CLIENT_ID'),
        'client_secret' => env('GITHUB_CLIENT_SECRET'),
        'redirect' => 'http://localhost:8083/auth/github/callback'
]

cors.php setting

[
    'paths' => ['api/*', 'sanctum/csrf-cookie', 'auth/github/callback'],

    'allowed_methods' => ['*'],

    'allowed_origins' => ['*'],

    'allowed_origins_patterns' => [],

    'allowed_headers' => ['*'],

    'exposed_headers' => [],

    'max_age' => 0,

    'supports_credentials' => true,
];

web.php

Route::get('/auth/{provider}/callback',[InvitationController::class, 'acceptOAuthOffer'])->name('oauth-accept');

auth.php

Route::get('invitation/{invitation}/{hash}', [InvitationController::class, 'offer'])
                ->middleware(['signed', 'throttle:6,1'])
                ->name('invitation.offer');

InvitationController.php

use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;

public function offer(Request $request): RedirectResponse
{
    // $invite is grabbed from the db in a code before the below code
    $provider = match($invitee->signup_channel) {
        Invitation::SIGNUP_TYPE_GOOGLE => 'google',
        Invitation::SIGNUP_TYPE_LINKEDIN => 'linkedin',
        Invitation::SIGNUP_TYPE_GITHUB => 'github'
    };

    return Socialite::driver($provider)->redirect();
}

public function acceptOAuthOffer(Request $request)
 {
        $provider = $request->route('provider');
        $oauthUser = Socialite::driver($provider)->user();

        $existingUser = User::where('oauth_id', $oauthUser->getId())->first();

        $user = null;

        if (empty($existingUser)) {

                $signup_channel = match ($provider) {
                    'google' => Invitation::SIGNUP_TYPE_GOOGLE,
                    'linkedin' => Invitation::SIGNUP_TYPE_LINKEDIN,
                    'github' => Invitation::SIGNUP_TYPE_GITHUB,
                };

                // create user
                $user = new User();
                $user->username = Str::before($oauthUser->email, '@');
                $user->first_name = $oauthUser->getName();
                $user->last_name = $oauthUser->getName();
                $user->email_verified_at = now();
                $user->email = $oauthUser->getEmail();
                $user->signup_channel = $signup_channel; // figure how to do this
                $user->oauth_id = $oauthUser->getId();
                $user->access_token = $oauthUser->token;
                $user->refresh_token = $oauthUser->refreshToken;
                $user->expires_in = $oauthUser->expiresIn;
                $user->password_reset = false;
                $user->password = Hash::make('');
                $user->status = User::STATUS_ACTIVE;
                $user->save();
            });
        }

        Auth::login($existingUser ?? $user);

        return redirect()->intended(RouteServiceProvider::HOME)
            ->with(['success' => 'You have logged in successfully!']);
    }

Again thanks for any help.
