Attempt to index "mouse" A NIL VALUE!?!?! Help with my gun script somebody pls?

here is the gun script that im making

-no raycasting, just a projectile

Here is the local script that's fires when Clicked

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

local tool = script.Parent.Parent
local remote = tool.Remotes.shootevent
local use = false
local cooldown = .5
local play = game.Players.LocalPlayer
tool.Activated:Connect(function()
    ---plocal animation = play.Character.Humanoid:LoadAnimation(tool.Animations.Animation)
    if use == false then    
    use = true
    ---animation:Play()
    wait(.5)
    ----animation:Stop()
    print("Slash")
    remote:FireServer(mouse)
    wait(cooldown)
    use = false
    end
    end)

and now the script that is supposed to get the bullet and shoot it at mouse direction (A script to shoot the gun when the event is fired)

local tool = script.Parent.Parent
local remote = tool.Remotes.shootevent
local hand = tool.Handle
local hit = false
---////--[Variables]--///-------------------------
local config = tool.Configuration
local ammo = config.Ammo
local Maxammo = config.MaxAmmo
local Animations = tool.Animations




remote.OnServerEvent:Connect(function(plr,mouse)
    local char = plr.Character or plr.CharacterAdded:wait()
    ----------=plr.Data:WaitForChild("Devilf").Value = "MaguFruit"
    local function GetBullet()
        local p = config.Bullet:Clone()
        return p
    end
local mh = mouse.hit
local bullet = GetBullet()
bullet.CFrame = script.Parent.Handle.CFrame * CFrame.new(char.HumanoidRootPart.CFrame.lookVector * 3)
    bullet.CFrame = CFrame.new(bullet.Position, mh.p)
    bullet.BodyVelocity.Velocity = bullet.CFrame.LookVector * 120

    bullet.Touched:Connect(function(hit)
    if hit and hit.Parent:FindFirstChild("Humanoid") then
        hit.Parent.Humanoid:TakeDamage()
    end
    end)
        end)

But for some reason when I clicked it sait "Attemped to index "Mouse as a Nil Value"... Why!? plz help me...
