Laravel 12 Cors- not working for me?

Apparently CORS just works with Laravel 12, but it doesn't work for me?

Starting from scratch, install/api config:publish cors

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

'allowed_methods' => ['*'],

'allowed_origins' => ['localhost:3000', '127.0.0.1:3000'],

'allowed_origins_patterns' => [],

'allowed_headers' => ['*'],

'exposed_headers' => [],

'max_age' => 600,

'supports_credentials' => false,

Simple routes:

Route::get('/show/{id}', [EmailController::class, 'show']);
Route::post('/search', [EmailController::class, 'search']);
Route::post('/search2', [EmailController::class, 'search2']);

simple app.php, does it need a middleware setup, or is it always there?

return Application::configure(basePath: dirname(__DIR__))
->withRouting(
    web: __DIR__.'/../routes/web.php',
    api: __DIR__.'/../routes/api.php',
    commands: __DIR__.'/../routes/console.php',
    health: '/up',
)
->withMiddleware(function (Middleware $middleware): void {
    //
})
->withExceptions(function (Exceptions $exceptions): void {
    //
})->create();

Postman call, works as expected, but as we know, ignores the origins header.

What am I missing?

Thanks for any help. Phil.
