Playing is not a valid member of AnimationTrack "Animation"

[spideyvhs]

Hey, I am having an issue with my script. It is supposed to give the player a stat whenever the animation that plays when they press C is currently playing, and when its not they stop getting currency. But whenever I run this script this error occurs,

Playing is not a valid member of AnimationTrack "Animation" 

But I loaded the animation to the humanoid??? If anyone can help me it would mean a lot, the script is below.

local event = script.Parent

debounce = false

event.OnServerEvent:Connect(function(plr)
	
	if debounce then return end

	local Char = plr.Character
	local Hum = Char:WaitForChild("Humanoid")
	local HumRP = Char:WaitForChild("HumanoidRootPart")
	
	local Chi = plr:WaitForChild("Stats"):WaitForChild("Chi")
	
	debounce = true
	
	local animation = Instance.new("Animation")
	animation.AnimationId = 'rbxassetid://13216568439'
	
	----------------------------------------------------------
	
	local MeditateAnimation = Hum:LoadAnimation(animation)
	
	MeditateAnimation:Play()
	
	Hum:GetPropertyChangedSignal("MoveDirection"):Connect(function()
		if Hum.MoveDirection.Magnitude > 0 then
			MeditateAnimation:Stop()
		end
	end)
	
	while MeditateAnimation.Playing do
		Chi.Value = Chi.Value + 1
	end
	
	MeditateAnimation.Stopped:Wait()
	wait(3)
	debounce = false
	
end)
