Table oldSlotData doesn't contain itemlink and if item doesn't exist, you can't get its itemlink.

However, if you need an itemlink, lets use workaround. I did something like that in my changes to Lost Treasure addon. Register for callback "SlotAdded" and then add itemlink to the slot table (in LT I'm adding itemId).

local function OnSlotAdded(bagId, slotIndex, slotData)
    slotData.itemLink = GetItemLink(bagId, slotIndex)
end
 
local function OnSlotRemoved(bagId, slotIndex, oldSlotData)
    d(zo_strformat("Item <<t:1>> was removed from the inventory.", oldSlotData.itemLink)
end
 
SHARED_INVENTORY:RegisterCallback("SlotAdded", OnSlotAdded)
SHARED_INVENTORY:RegisterCallback("SlotRemoved", OnSlotRemoved)
