getItemAvailability Unexpected Error 703

Hello,

I am having an issue with the getItemAvailability method. It works with most items, but when a new item was added, I now get Unexpected Error 703. I looked to see if there was anything noticably different between this item and other items that work, but can't see any significant difference.

Here is my code. DisplayName is the NetSuite internal ID.

     Public Function GetNetSuiteInformation(ByRef Product As PSOrderDetailsItemType) As Boolean          Dim availabilityResult As GetItemAvailabilityResult = Nothing          Dim itemAvailabilityFilter As ItemAvailabilityFilter = Nothing          Dim Record As RecordRef = New RecordRef()          Try              itemAvailabilityFilter = New ItemAvailabilityFilter                Record.internalId = Product.NetSuiteItemInformation.DisplayName              Record.type = RecordType.inventoryItem              Record.typeSpecified = True                Dim RecordList() As RecordRef = {Record}                itemAvailabilityFilter.item = RecordList                RecordList = Nothing                availabilityResult = Me.getItemAvailability(Me.NSService, itemAvailabilityFilter)                If availabilityResult.status.isSuccess Then                    Product.NetSuiteItemInformation.ItemExists = True                  Dim availabilityItemList() As ItemAvailability = availabilityResult.itemAvailabilityList                  'Dim availabilityItem As ItemAvailability = availabilityListItem.GetValue(0)                  Dim availabilityItem As ItemAvailability = CType(availabilityItemList.GetValue(0), ItemAvailability)                    Product.NetSuiteItemInformation.QuantityAvailable = availabilityItem.quantityAvailable                  Product.NetSuiteItemInformation.QuantityBackordered = availabilityItem.quantityBackOrdered                  Product.NetSuiteItemInformation.QuantityCommited = availabilityItem.quantityCommitted                  Product.NetSuiteItemInformation.QuantityOnHand = availabilityItem.quantityOnHand                  Product.NetSuiteItemInformation.QuantityOnOrder = availabilityItem.quantityOnOrder                  Product.NetSuiteItemInformation.ItemType =
