Can you help me with my gun script? It doesn't shoot after click.

Yo, i'm back after 6 months and I came across a problem with my gun script, every time I shoot at the enemy it doesn't work, here's the part of the code that i think has that problem.

Server Script UPDATED

local event = game.ReplicatedStorage.ShootGun
local damage = math.random(20,60)
local range = 50 
local gunshot = script.Parent.gunshot

function createBeam(pos)
	print(8)
	local part = Instance.new("Part", workspace)
	part.Position = pos
	print(9)
	local at1 = Instance.new("Attachment", part)
	local at2 = Instance.new("Attachment", script.Parent.Handle)
	print(10)
	local beam = Instance.new("Beam", script.Parent.Handle)
	beam.Texture = "http://www.roblox.com/asset/?id=1274378728"
	print(11)
end


event.OnServerEvent:Connect(function(player, mousePos, originPos)
	print(1)
	local direction = (mousePos - originPos).Unit * range  
	print(2)
	local result = workspace:Raycast(originPos, mousePos)
	if result then
		print(3)
		print(4)
		local character = result.Instance.Parent 
		local humanoid = character:FindFirstChild("Humanoid")
		print(5)
		if humanoid then 
			print(6)
			humanoid:TakeDamage(damage)
		end
		print(7)
		createBeam(result.Instance.Position)
		gunshot:Play()
	end
end)

Local Script

local tool = script.Parent 
local origin = tool:WaitForChild("Handle").Position

local player = game.Players.LocalPlayer 
local mouse = player:GetMouse()

local event = game.ReplicatedStorage.ShootGun


local recoil = false 
local recoilTime = 0.4
tool.Activated:Connect(function()
	if recoil then return end 
	recoil = true 

	local mousePosition = mouse.Target.Position

	event:FireServer(mousePosition, origin)

	wait(recoil)
	recoil = false 
end)

And What's the Error
