php - Laravel session data empty after user login

I am using laravel version 6.17.0.

If I put data to sessionSession::put('cart_merge', $data) inauthenticated() method ofAuthenticatesUsers trait and I try to get them withSession::get('cart_merge') in Controller, the session is empty. If I doSession::get('cart_merge') right after insertion inauthenticated() method, they are still there.

I tried grouping routes as adviced in https://stackoverflow.com/a/35140419/5821265 but it didn't help.

Why do session doesn't make it untill Controller?

AuthenticatesUsers.php:

protected function authenticated(Request $request, $user)
{
    $cart = getCart::getCart();
    $savedCart = $user->cart;

    if (empty($cart['cart'])){  // Shopping cart is empty
        $cart = [];
        foreach ($savedCart as $item) {
            $product = Product::where('id', $item->id)->where('visibility', 1)->where('stock', '>', 0)->first();
            if (is_null($product)) {
                continue;
            }
            if ($item->pivot->amount > $product->stock){
                $cart[$item->id]['amount'] = $product->stock;
            }
            else {
                $cart[$item->id]['amount'] = $item->pivot->amount;
            }
            $cart[$item->id]['name'] = $product->name;
            $cart[$item->id]['url'] = $product->url;
            $cart[$item->id]['image'] = $product->image;
        }
        Session::put('cart', $cart);
    }
    else {  // There are some items in shopping cart.
        if ($savedCart->isEmpty()){     // User doesn't have any items saved in DB from last session.
            foreach ($cart['cart'] as $item_id => $item){
                DB::table('product_user')->insert([
                    'user_id' => $user->id,
                    'product_id' => $item_id,
                    'amount' => $cart['cart'][$item_id]['amount'],
                    'type' => 0
                ]);
            }
        }
        else {  // User has saved items in DB from last session.
            Session::put('cart_merge', $savedCart->toArray());
            // if I do Session::get('cart_merge') here, the data are correct.
        }
    }
}
Copy code

SystemController.php:

class SystemController extends Controller
{
    public function index(){
        $data = Session:get('cart_merge');
        dd($data);
        // if I do Session::get('cart_merge') here, null is returned instead of data.
    }
}
Copy code

web.php:

Route::group(['middleware' => ['web']], function () {
    Route::get('/', 'SystemController@index');
    Auth::routes();
});
Copy code
