Or maybe it wasn't a type-o.
Does it still work if you do something like:

return _lItemLink and GetMyLinkItemInfo(_lItemLink) or GetItemInfo(_iBagId, _iSlotId)

Sorry I should have just posted the actual code to begin with.

The idea is to call one function GetMyItemInfo(..) to get an items info whether you pass in a bag,slot or link:

local function GetMyLinkItemInfo(_lItemLink)
    local sIcon, iSellPrice, bMeetsUsageRequirement, iEquipType, iItemStyle = GetItemLinkInfo(_lItemLink)
    local iItemQuality = GetItemLinkQuality(_lItemLink)
-- I know iStack & bLocked are not defined & return nil --
-- I'm ok with that, nothing wrong with doing that right ? --
    return sIcon, iStack, iSellPrice, bMeetsUsageRequirement, bLocked, iEquipType, iItemStyle, iItemQuality
end
 
local function GetMyItemInfo(_iBagId, _iSlotId, _lItemLink)
-- These two below work
    --return GetMyLinkItemInfo(_lItemLink) 
    --return GetItemInfo(_iBagId, _iSlotId)
-- But this one doesn't
    return _lItemLink and GetMyLinkItemInfo(_lItemLink) or GetItemInfo(_iBagId, _iSlotId)
end

and then calling the following fails:

-- Whether I call it with a bagId, slotId or Link they both fail at the same place --
    local sIcon, iStack, iSellPrice, bMeetsUsageRequirement, bLocked, iEquipType, iItemStyle, iItemQuality = GetmyItemInfo(iBagId, iSlotId, nil)
    local sIcon, iStack, iSellPrice, bMeetsUsageRequirement, bLocked, iEquipType, iItemStyle, iItemQuality = GetmyItemInfo(nil, nil, lLink)
 
    d("sIcon: "..sIcon)
-- I know iStack can be nil if I pass in a link, thats ok --
    if iStack then d("iStack: "..iStack) else d("iStack: Nil") end
 
--***************************************************--
-- iSellPrice: Fails with "Operator .. not supported for string .. nil" --
    d("iSellPrice: "..iSellPrice)
--***************************************************--
 
 
    d("bMeetsUsageRequirement: "..tostring(bMeetsUsageRequirement))
-- I know bLocked can be nil if I pass in a link, thats ok --
    if bLocked then d("bLocked: "..tostring(bLocked)) else d("bLocked: Nil") end
    d("iEquipType: "..iEquipType)
    d("iItemStyle: "..iItemStyle)
    d("iItemQuality: "..iItemQuality)
