chosen item coming back with argument missing or nil?

local function LoadItems()
    for _, v in pairs(workspace:GetDescendants()) do
        if v:IsA("Model") and v.Name == "ItemRoom" then
            if not v:FindFirstChild("Item") then
                print("no item bool")
                local ItemBool = Instance.new("BoolValue")
                ItemBool.Name = "Item"
                ItemBool.Parent = v
                local ItemFind, i = chooseRandomItem()
                local chosenItem = ReplicatedStorage.Items:FindFirstChild(ItemFind) -- err here...
                local ClonedItem = chosenItem:Clone()
                ClonedItem.Parent = v
                ClonedItem:SetPrimaryPartCFrame(v.ItemLocation.CFrame)
                ItemDesc()
                if chosenItem:FindFirstChild("OneUse") then
                    table.remove(Items,i)
                    end
                    end
                end
            end
        end
