Firetrail power not following mouse?

What im trying to achieve here is when you press a key bind, a fire trail will clone into workspace wherever your mouse goes. But it stays in one place and does not move with the mouse. Can anyone help?

local ReplicatedS = game:GetService("ReplicatedStorage")
local PainEvent = ReplicatedS:WaitForChild("firetrail")
local ts = game:GetService("TweenService")

PainEvent.OnServerEvent:Connect(function(player, mouse)
	local players = game.Players
	local player = players.LocalPlayer
	local victim = mouse.Parent:FindFirstChild("Humanoid")
	local victimCharacter = mouse.Parent
	local pained = victimCharacter:FindFirstChild("Pained")
	local h = victimCharacter:findFirstChild("Humanoid")
	local Player = victimCharacter
	local Char = victimCharacter
	local victimplayer = game.Players:GetPlayerFromCharacter(victimCharacter)
	local timeRemaining = 10
	local bonniefire = game.ServerScriptService.GameFolder.Spells.CharacterSpells.Bonnie.firetrail.firetrailpart
	
	

	while timeRemaining > 0 do
		print("Seconds remaining: " .. timeRemaining)
		wait(0.1)
		timeRemaining = timeRemaining - 1	
		local firetrail = bonniefire:Clone()
		firetrail.Parent = game.Workspace
		firetrail.Position = mouse.Hit.Position
			--firetrail:Destroy()
end
	wait(11)
	local fires = game.Workspace:FindFirstChild("FireTrail")
	fires:Destroy()
	
end)

The mouse object only exists on the client (as it is instantiated by the client). From the server’s perspective the ‘mouse’ variable points to nil.

What you could do is use a ‘RemoteFunction’ object and invoke the client for its mouse’s position instead.
