Hello so I have this remote function that needs the players mouse, the arguments are:
Player, Tool, Handle, Gunshot, TracerPart, Mouse

My local script provides it with:
Tool, Handle, Handle.Gunshot, TracerPart, Mouse

However the Server script keeps outputting
ServerScriptService.GunSystem:53: Cannot find Mouse

Script

function cast(Player, Tool, Handle, Gunshot, TracerPart, Mouse)
	local Cooldown = guncooldownlist[Tool.Name]
	print(Cooldown)
	local Damage = damagelist[Tool.Name]
	print(Damage)
	local Spread = spreadlist[Tool.Name]
	print(Spread)
	
	if Spread == nil or Damage == nil or Cooldown == nil then
		error("Cannot find gun values")
	end
	
	if Mouse == nil then
		error("Cannot find Mouse")
	end
	
	local ShootAtPart = Instance.new("Part")
	ShootAtPart.CanCollide = false
	ShootAtPart.Anchored = true
	ShootAtPart.Transparency = 1
	ShootAtPart.Size = Vector3.new(1,1,1)
	ShootAtPart.Parent = workspace
	
	local rng = math.random(1,2)
	if rng == 1 then
		ShootAtPart.CFrame = Mouse.Hit / math.random(0, Spread)
	else
		ShootAtPart.CFrame = Mouse.Hit * math.random(0, Spread)
	end
	
	local ray = Ray.new(TracerPart.CFrame.Position, (ShootAtPart.CFrame.Position - TracerPart.CFrame.Position).unit * 3000)
	local part, position = workspace:FindPartOnRay(ray, Player.Character)
	
	if part then
		local human = part.Parent:FindFirstChild("Humanoid")
		if not human then
			human = part.Parent.Parent:FindFirstChild("Humanoid")
		end
		
		if human then
			human:TakeDamage(Damage)
		end
	end
	
	local light = Instance.new("PointLight")
	light.Parent = Handle
	light.Brightness = 12	
	
	local sparks = Sparks:Clone()
	sparks.Parent = Handle
	
	local smoke = Smoke:Clone()
	smoke.Parent = ShootAtPart
	smoke.Position = ShootAtPart.Position
	
	spawn(function()
		wait(0.7)
		smoke.Hole.Enabled = false
	end)
	
	Debris:AddItem(light, 0.05)
	Debris:AddItem(ShootAtPart, 1)
	Debris:AddItem(smoke, 1.5)
end

HitCheck.OnServerInvoke = cast

		    GUI.CurrentAmmo.Text = Ammo.Value
		    ScreenGui.CurrentAmmo.Text = Ammo.Value

I have found a work around to this and no longer require a response.

Mind posting what your workaround was so that others encountering this same issue can know what you did to resolve the issue? Please also mark that followup as the solution so others can easily access the post they need to follow to fix their own implementation.

I needed the mouse on the server to check Mouse.Hit, so instead of trying to give the server the mouse I just remove the Mouse in InvokeServer and replace it with the Mouse.Hit value, if I wanted more values I would have to do the same thing making it inefficient but all I care is that it works.
