when animating the enemies in a tower defense game this error shows up:
Attempt to connect failed: Passed value is not a function
when i hover over it, no script or line shows up however i assume the error is because of this script as it started showing up when i made this script:

local function animateMob(object)
	local humanoid = object:WaitForChild("Humanoid")
	local animationsFolder = object:WaitForChild("Animations")
	
	if humanoid and animationsFolder then
		local walkAnimation = animationsFolder:WaitForChild("Walk")
		if walkAnimation then
			local animator = humanoid:FindFirstChild("Animator") or Instance.new("Animator", humanoid)
			local walkTrack = animator:LoadAnimation(walkAnimation)
			walkTrack:Play()
		end
	else
		warn("No humanoid/animation folder for", object.Name)
	end
end

workspace.Mobs.ChildAdded:Connect()

keep in mind this is a local script.

For the love of god, PLEASE DOUBLE CHECK YOUR CODE, especially when the error message couldn’t be more clear about what is going wrong.

You forgot to actually include the function for the :Connect method. It is empty bro
