bad argument #2 to '?' (string expected, got Object)

i was make a remote-function so the inventor script can show images but on line 17 is gives the error bad argument #2 to '?' (string expected, got Object) but as far is as i know its getting a string.

client side code:

local IOS = 0
local Xs = 0.0
local Ys = 0.377
local placeholeder = script.Parent.Parent.Defal.ImageLabel
function items()
    for _, child in pairs(script.Parent:GetChildren()) do
        if child.Name ~= "Itmesscripts" then
            child:Destroy()
        end
        IOS = 0
        Ys = 0.027
        Xs = 0.039
    end
    for _, child in pairs(game.Players.LocalPlayer.items:GetChildren()) do
        if child.Value > 0 then
            local ChildName = child.Name
            local NAME = game.ReplicatedStorage.GetItemNameAndImg:InvokeServer(ChildName)
            placeitem(NAME[1],child.Name,NAME[2])
        end
    end
end

function placeitem(NAME,ID,img)
    local itme = placeholeder:Clone()
    itme.Parent = script.Parent.Parent.ScrollingFrame
    local XYs = UDim2.new(Xs,0, Ys, 0)
    itme.Position = XYs
    IOS = IOS + 1
    if Xs == 0.0 then
        Xs = 0.562
    else 
        Xs = 0
        Ys = Ys + 377
    end
    itme.Name = NAME
    itme.Image = "rbxassetid://" + img
    local amout = game.Players.LocalPlayer.items[ID].Value
    itme.TextLabel.Text = NAME .. "\n" .. amout
    itme.Visible = true
end

while true do
    items()
    wait(1)
end

Sever side code:

function GetItemNameAndImg(ID) 
    return({game.ServerStorage.items[ID].name.Value,game.ServerStorage.items[ID].LogoID.Value})
end
game.ReplicatedStorage.GetItemNameAndImg.OnServerInvoke = GetItemNameAndImg
