[Solved]How can I fix my animation script?

I used this script to play an animation:

local function equip()
	equipped = true
	
	--//Get humanoid
	local character = player.Character or player.CharacterAdded:Wait()
	local humanoid = character:WaitForChild("Humanoid")
	
	if humanoid then
		--//Load animations
		pcall(function()
			--//Hold animation
			holdTrack = humanoid:LoadAnimation(holdAnim)
			holdTrack:Play()
		end)
end
end

But I get this error: 10:12:27.271 - Animation failed to load in "Workspace.CaptainD_veloper.Assualt Rifle.Animations.Hold.AnimationId": Animation failed to load
