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
