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)
