Problem with GetItemQualityColor

[Mayron]

Hi everyone,

I have a bug which I cannot seem to fix or figure out what is causing it. I have this code:

local function updateIcons()
    if not PaperDollFrame:IsShown() then return end
    
    for i, slot in next, slots do
        if i == 18 then i = 19 end
        local link = GetInventoryItemLink("player", i)
        local slotName = _G["Character"..slot.."Slot"]
        local iconBorder = _G["mui_" .. "Character" .. slot .. "Slot"]          
        
        if link then
            slotName.icon:SetAlpha(1)
            local r, g, b, _ = GetItemQualityColor(select(3, GetItemInfo(link)))
            iconBorder:SetBackdropBorderColor(r, g, b, 1)
            iconBorder:SetBackdropColor(r,g,b,0.2)          
        end
    end
end

running with this:

PaperDollFrame:HookScript("OnShow", updateIcons)
    ef:RegisterEvent("UNIT_INVENTORY_CHANGED")
    ef:SetScript("OnEvent", updateIcons)

in a PLAYER_LOGIN event. However this line:

local r, g, b, _ = GetItemQualityColor(select(3, GetItemInfo(link)))

shows this lua error each time I login:

It is just to get item icons fro mthe character frame and color the border depending on the items rarity value. I am not sure why this is happening because the player has logged in and it does actually work, but I get the error saying I'm using it incorrectly? I'm not sure and hopefully the code makes sense to know what I am trying to do. If anyone has any advice or a fix for me then that would be brilliant but if you need extra information let me know. Thanks in advance guys!
