CORS Error in Helper Class

[attiqdev]

Hi Guys, thanks for this code sample I am using your sample @MrYossu but I am facing one issue can you please help me with this. When I am calling the CreateOrderResponse orderResponse = await _client.OrdersApi.CreateOrderAsync(orderRequest); in SquareHelper.cs line 139, I am getting this error

"Access to fetch at 'https://connect.squareupsandbox.com/v2/orders' from origin 'https://localhost:44309/' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status."

can you please tell me what else should I do to reslove this?

Actually, I am using this code in the blazer application the same as you are using but when I reach this line where I create and get the order in the helper class it's giving me the exception for CORS. So I am wondering how its working for you with doing anything for CORS
