attempt to call a RBXScriptConnection value?

Ok so im trying to make a titan shifting script from the anime "Attack on Titan"

the script works but it keeps saying "attempt to call a RBXScriptConnection value" on line 3

sorry if the script looks bad im still learning but it works the way i want it to

local Ball = game.ReplicatedStorage.TransformationBall:Clone()

game.ReplicatedStorage.HasShifted.OnServerEvent:Connect(function(Player)
	game.StarterPlayer.StarterPlayerScripts.ButtonPressed.Disabled = true
	game.StarterPlayer.StarterPlayerScripts.RunningNormal.Disabled = true
	Player:WaitForChild("Titan").Transforming.Value = true
	wait(3)
	print(Player.Name.." it Now Shifting")
	Ball.Parent = workspace
	Ball.Position = workspace:FindFirstChild(Player.Name).HumanoidRootPart.Position
	
	workspace.SoundEffects.Transform:Play()
	
	game.Workspace:FindFirstChild(Player.Name).Shirt.ShirtTemplate = " "
	game.Workspace:FindFirstChild(Player.Name).Pants.PantsTemplate = " "

	game.Lighting.TransformationColorCorrection.Enabled = true

	wait(0.3)

	game.Lighting.TransformationColorCorrection.Enabled = false
	
	local bds = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").BodyDepthScale
	local bhs = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").BodyHeightScale
	local bps = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").BodyProportionScale
	local bts = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").BodyTypeScale
	local bws = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").BodyWidthScale
	local hs = game.Workspace:FindFirstChild(Player.Name):WaitForChild("Humanoid").HeadScale
	
	local TransformBall = game:GetService("TweenService")
	local TransBall = workspace:WaitForChild("TransformationBall")
	local info = TweenInfo.new(5, Enum.EasingStyle.Bounce , Enum.EasingDirection.Out)
	local TweenGoal = {Size = Vector3.new(12, 12, 12),}
	local BallAnimation = TransformBall:Create(TransBall, info, TweenGoal)
	
	local fadeinfo = TweenInfo.new(1, Enum.EasingStyle.Sine , Enum.EasingDirection.Out)
	local FadeGoal = {
		Size = Vector3.new(14, 14, 14),
		Transparency = 1
	}
	
	local fadeAnimation = TransformBall:Create(TransBall, fadeinfo, FadeGoal)
	BallAnimation:Play()
	while true do
		wait(0)
		bds.Value = bds.Value + 0.1
		bhs.Value = bhs.Value + 0.1
		bps.Value = bps.Value + 0.1
		bts.Value = bts.Value + 0.1
		bws.Value = bws.Value + 0.1
		hs.Value = hs.Value + 0.1
		if bds.Value >= 5 and bhs.Value >= 5 and bps.Value >= 5 and bts.Value >= 5 and bws.Value >= 5 and hs.Value >= 5 then
			break
		end
	end
	print("Broke")
	wait(2)
	fadeAnimation:Play()
	wait(1.5)
	TransBall:Destroy()
	workspace:FindFirstChild(Player.Name).Humanoid.WalkSpeed = 64
	Player:WaitForChild("Titan").Transforming.Value = false
end)



{
	Size = Vector3.new(12, 12, 12),
	Transparancy = 1
