Script errors and outputs an "animation failed to load in..." error?

I have this script that allows the player to press E and punch which plays an animation and also does damage. It works fine in studio, however when played online it gives me an error that says:

Animation "..." failed to load in "..." :Animation Failed to load.

I have a local script and a regular script that uses remote events to communicate with each other.

Here is the local script:

local UIS = game:GetService("UserInputService")

local canPunch = true

local function onKeyPressed(input)
	if input.KeyCode == Enum.KeyCode.E and canPunch then
		script.Parent:WaitForChild("PunchEvent"):FireServer()
		canPunch = false
		local punchRate = 1
		wait(punchRate)
		canPunch = true
	end
	
end

UIS.InputBegan:Connect(onKeyPressed)

And here is the server script:

local punchEvent = script:WaitForChild("PunchEvent")
local punchAnimation = script:WaitForChild("Punch")
local canHurt = true
local isSwinging = false

punchEvent.OnServerEvent:Connect(function(player)
	
	local humanoid = script.Parent:WaitForChild("Humanoid")
	local animation = humanoid:LoadAnimation(punchAnimation)
	
	animation:Play(0.4, 1, 1)
	wait(0.25)
	animation:AdjustSpeed(0)
	wait(0.2)
	animation:AdjustSpeed(2)
	isSwinging = true
	canHurt = true
	wait(0.3)
	isSwinging = false
	
	local rightHand = script.Parent:WaitForChild("RightHand")

	rightHand.Touched:Connect(function(hit)
		
		if not isSwinging then return end
		if not canHurt then return end
		
		canHurt = false		
		
		if hit and hit.Parent:FindFirstChild("Humanoid") then
			local human = hit.Parent:FindFirstChild("Humanoid")
			human:TakeDamage(10)
		end
		
		wait(0.3)
		canHurt = true
		
		
	end)

	
end)

This error means the animation could not be used. One of two scenarios can cause this error:

A. The animation must be owned by the game/group creator or ROBLOX.

B. The animation has been deleted by ROBLOX.
