I am running into an issue with the HttpContext.Current is set null in my Custom Info providers when I try to access information from a cart, e.g. UnitTotalTaxInMainCurrency of a ShoppingCartItemInfo, from an async task in the integration bus. I need to get a file from the server using HttpContext.Current.Server.MapPath() but because HttpContext.Current is null I cannot read in the file.

Does anyone know of a way around this issue?
