Hi,

We have a 7.5 Episerver CMS and Commerce.

 The site has worked for over 8 years – and suddenly on the 16th Jan 2022 the commerce side of the website stopped working.

 When we add in an item to the Cart the cart is full – when it hits ListItemsSimpleView.ascx.cs in the BINDDATA method the Cart is still full but as soon as it hits this function

 CartHelper.RunWorkflow(Constants.CartValidateWorkflowName); - the workflow name is “CartValidate”.

 The Cart is empty 

 I have rolled back the code to a code sample of 2020 (2 years old) and it still throws the same error. Which is very odd.

 Can I ask – does CartHelper.RunWorkflow (which is part of Mediachase.Commerce.Orders.Managers) talk to any external APIs such as FIND or any EpiServer API that may have stopped working/de-commissioned OR changed?

SAMPLE OF CODE

private void BindData()

        {

            var isEmpty = CartHelper.IsEmpty;

            // Make sure to check that prices has not changed

            if (!isEmpty)

            {

                // restore coupon code to context

                string couponCode = Session[Constants.LastCouponCode] asstring;

                if (!String.IsNullOrEmpty(couponCode))

                {

                    MarketingContext.Current.AddCouponToMarketingContext(couponCode);

                }

                CartHelper.Cart.ProviderId = "FrontEnd";

                CartHelper.RunWorkflow(Constants.CartValidateWorkflowName);

                // If cart is empty, remove it from the database

                isEmpty = CartHelper.IsEmpty;

                if (isEmpty)

                    CartHelper.Delete();

                CartHelper.Cart.AcceptChanges();

            }

            if (!isEmpty)

            {

                string ProductName = "";

                try

                {

                    foreach (var v in CartHelper.LineItems)

                    {

                        var ce = CatalogContext.Current.GetCatalogEntry(v.ParentCatalogEntryId);

                        if (ce != null)

                        {

                            if (ce.Name != null && ce.Name != "")

                            {

                                ProductName = ce.Name;

                                break;

                            }

                        }

                    }

                    if (ProductName != "")

                    {

                        litEventName.Text = "<h2>" + ProductName + "</h2><hr/>";

                    }

                }

                catch (Exception ex)

                {

                    SendUserEmail(ex.Message, "ERROR BINDING");

                }

                lvCartItems.DataSource = CartHelper.LineItems;

                _promotionResult = CartHelper.GetPromotions();

            }

            lvCartItems.DataBind();

        }
