Why are these arguments nil?

This script should be passing 2 values when f is pressed , however every time I press f, the arguments return nil

Argument 1 missing or nil

Can anyone tell me why? Thanks in advance!

local Hotbar =  player.PlayerGui.HotbarUI.Hotbar
   local e = game.ReplicatedStorage:WaitForChild("ChangeToolEvent")

function onKeyPress(inputObject, gameProcessedEvent)
if  inputObject.KeyCode == Enum.KeyCode.W then
        script.Asset.Value = ("Forward")
        elseif  inputObject.KeyCode == Enum.KeyCode.S then
        script.Asset.Value = ("Backward")
elseif  inputObject.KeyCode == Enum.KeyCode.F then
    local V1 = Hotbar.CurrentSlot.Itemtype.Value
    local V2 = Hotbar.CurrentSlot.CurrentItem.Value
        e:FireServer(V1,V2)
end

end
        game:GetService("UserInputService").InputBegan:connect(onKeyPress)

function weld(p1,p2,c0)
    local w = Instance.new("Weld",p1)
    w.Part0 = p1
