Need help with throwable

[CoffeeEnjoyerr]

I have a throwable grenade that you can throw. And it seems fine, but when I try to throw it after player dies it gives me error like this (and somewhy gives it twice):

Local script:

local cas = game:GetService("ContextActionService")
local tool = script.Parent
local players = game:GetService("Players")
local player = players.LocalPlayer
local character = player.Character or player.CharacterAppearanceLoaded:Wait()
local event = tool:FindFirstChild("ThrowEvent")
local part = tool:FindFirstChild("Handle")

local function bindFunc()
	local mouse = player:GetMouse()
	event:FireServer(mouse.Hit.Position, part)
	player.CameraMode = Enum.CameraMode.Classic
end

tool.Equipped:Connect(function()
	player.CameraMode = Enum.CameraMode.LockFirstPerson
	cas:BindAction("Throw", bindFunc, true, Enum.UserInputType.MouseButton1)
end)

tool.Unequipped:Connect(function()
	player.CameraMode = Enum.CameraMode.Classic
	cas:UnbindAction("Throw")
end)

Server script:

local tool = script.Parent

event.OnServerEvent:Connect(function(player, pos, p)
	local part = p:Clone()
	part.Parent = workspace
	part.CanCollide = true
	part.CFrame = CFrame.lookAt(part.Position, pos)
	part.AssemblyLinearVelocity = part.CFrame.LookVector * 70
	tool:Destroy()
end)
