Laravel cart page product quantity update with ajax problem - ajax

Question

I want to update my cart page product quantity with ajax but not working. My cartController is not getting any response. I went to the browser network option and saw that Ajax has sent its data but I am not getting any response from the server
View file:
#foreach ($cartProduct as $cartsProduct)
<tr class="cartPage">
<td class="shoping__cart__item">
<img src="{{asset('upload/'.$cartsProduct->products->product_future_image)}}" alt="">
<h5>{{$cartsProduct->products->product_name}}</h5>
</td>
<td class="shoping__cart__price">
${{$cartsProduct->product_price}}
</td>
<td class="shoping__cart__quantity">
<div class="quantity">
<input type="hidden" name="CartID" class="productID" value="{{$cartsProduct>id}}">
<div class="pro-qty">
<input type="text" class="productQty" name="CartQuantity" value="{{$cartsProduct->product_quantity}}">
</div>
</div>
</td>
<td class="shoping__cart__total">
${{$cartsProduct->product_quantity * $cartsProduct->product_price}}
</td>
<td class="shoping__cart__item__close">
<span class="icon_close"></span>
</td>
</tr>
#endforeach
ajax code:
$(document).ready(function(){
$('.updateQuantiy').click(function(e){
e.preventDefault();
var cartID = $(this).closest('.cartPage').find('.productID').val();
var productQuantity = $(this).closest('.cartPage').find('.productQty').val();
var data = {
'_token' : "{{csrf_token()}}",
'cartID' : cartID,
'productQuantity' : productQuantity,
};
$.ajax({
url : '/cart-quantity-update',
type : 'POST',
data : data,
success: function(response){
window.location.reload();
toastr.options = {"closeButton": true, "progressBar": true }
toastr.success(response.status);
}
})
});
});
Route:
Route::post('/cart-quantity-update', [CartController::class, 'updateQuantity']);
cartController:
public function updateQuantity(Request $request){
$CartID = $request->post('CartID');
$cartQuantity = $request->post('CartQuantity');
$cartUpdate = Cart::where('id', $CartID)->where('user_ip', request()->ip());
$cartUpdate->product_quantity = $cartQuantity;
$cartUpdate->save();
return response()->json(['status' => 'Product Quantity Updated']);
}
I want to update cart quantity from here.
