RemoteFunction/ClientInvoke is not working?

i am trying to recycle Kizzuny's "Blizzard staff [Revamp]" gear's script (the placement of the Projectiles and velocity) but the invoke doesn't work. :/

I don't really know what i am doing wrong but you guys can show me!

ServerScript:

local Part = Instance.new("Part") -- the part
		Part.Size = Vector3.new(5,5,5)
		Part.Color = Color3.fromRGB(255, 255, 0)
		Part.Transparency = .3
		Part.Shape = Enum.PartType.Ball
		Part.Parent = workspace
		Part.Anchored = false
		Part.CastShadow = false
		Part.CanCollide = false
		
		local BodyVelocity = Instance.new("BodyVelocity")
		BodyVelocity.Parent = Part
		BodyVelocity.MaxForce = Vector3.new(1,1,1)*math.huge
		BodyVelocity.P = 1000000

		Part.Position = (Root.Position + Vector3.new(Random.new(tick()):NextInteger(-60, 60), Random.new(tick()):NextInteger(80, 100), Random.new(tick()):NextInteger(-60, 60)))
		Part.CFrame = (CFrame.new(Part.Position, Tool.DirectionInvoker:InvokeClient(Player).Position)) * (CFrame.Angles(math.rad(90),math.rad(-90),math.rad(180))) -- ClientInvoke is going wrong
		Part.Parent = workspace
		BodyVelocity.Velocity = (Part.Position - Tool.DirectionInvoker:InvokeClient(Player).Position).Unit * -125
	end

LocalScript:

local DirectionInvoker = Tool:WaitForChild("DirectionInvoker", 10)
DirectionInvoker.OnClientInvoke = function()
	local NewPlayer = game.Players.LocalPlayer or Player
	if NewPlayer and NewPlayer:IsA("Player") then
		local Mouse = NewPlayer:GetMouse()
		if Mouse then
			local Table = {
				Hit = Mouse.Hit,
				Position = Mouse.Hit.p,
				Target = Mouse.Target
			}
			return Table
		end
	end
	local Table = {
		Hit = nil,
		Position = Vector3.new(0,0,0),
		Target = nil
	}
	return Table
end

This is the Error: Argument 1 missing or nil, I just assume that its the CientInvoke going wrong for some reason.
