I can't figure out what I am doing wrong Lecture 176

[althepal78]

I don't know what happened in this section,
<input value="@Model.OrderHeader.OrderDate.ToShortDateString()" readonly type="text" class="form-control" /> on my details page I get this error and it just started. I don't know how the reference is null if it i showing properly on the page
System.NullReferenceException: 'Object reference not set to an instance of an object.', Yet you can see it working properly before I press the update order details button. I can't figure out why it is null and I am getting frustrated because I just got here and figured out everything else I had errors with. I have it on this repository https://github.com/althepal78/MellysUnderGroundCuisineMUCDB
because I am going to change it from book to my friends site ;)

This is what I had to do to make this work. I wish people would answer. It was more of a mess up in the payment thing so it ruined everything.

  public IActionResult OrderConfirmation(Guid id)
        {
            OrderHeader orderHeader = _unitOfWork.OrderHeader.GetFirstOrDefault(u => u.Id == id, includeProperties: "ApplicationUser");
            if (orderHeader.PaymentStatus != StaticDetails.PaymentStatusDelayedPayment)
            {
                var service = new SessionService();
                Session session = service.Get(orderHeader.SessionId);
                
                if(orderHeader.PaymentIntentId == null)
                {
                    orderHeader.PaymentIntentId = session.PaymentIntentId;
                    _unitOfWork.OrderHeader.Update(orderHeader);
                    _unitOfWork.Save();
                }
                //check the stripe status
                if (session.PaymentStatus.ToLower() == "paid")
                {
                    _unitOfWork.OrderHeader.UpdateStatus((Guid)id, StaticDetails.StatusApproved, StaticDetails.PaymentStatusApproved);
                    _unitOfWork.Save();
                }
            }
            
            _emailSender.SendEmailAsync(orderHeader.ApplicationUser.Email, "New Order - Bulky Book", "<p>New Order Created</p>");
            List<ShoppingCart> shoppingCarts = _unitOfWork.ShoppingCart.GetAll(u => u.ApplicationUserId ==
            orderHeader.ApplicationUserId).ToList();
            _unitOfWork.ShoppingCart.RemoveRange(shoppingCarts);
            _unitOfWork.Save();
            return View((Guid)id);
        }
