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)
		

	

--The Event

function weld(p1,p2,c0)
	local w = Instance.new("Weld",p1)
	w.Part0 = p1
	w.Part1 = p2
	w.C0 = c0 or p1.CFrame:inverse() * p2.CFrame
	return w
end



local event = game.ReplicatedStorage:WaitForChild("ChangeToolEvent") event.OnServerEvent:connect(function(player,arguments)
