I have a death effect and sometimes it works but sometimes it doesn’t. I don’t understand why?

Failed to load animation with sanitized ID rbxassetid://18661047774: Animation failed to load

[deaconstjohn03 (Colorato)]

it just doesnt load the animation in time, nothing to worry but very annoying

Thanks, I’m not sure it is that because whever I just test it in studio it works perfectly but whenever I go in game it doesn’t ever work. So i think something else might be an issue

game.ReplicatedStorage.DiedRE.OnServerEvent:Connect(function(plr,animation)

	if not plr.Character or not plr.Character:FindFirstChild("Humanoid") then return end

	local char = plr.Character
	local humanoid = char.Humanoid

	char.HumanoidRootPart.Anchored = true

	local animator = humanoid:WaitForChild("Animator")
	
	local kickAnimationTrack = nil

	kickAnimationTrack = animator:LoadAnimation(animation)
	
	task.wait(0.1)
	
	kickAnimationTrack:Play()
	
	kickAnimationTrack.Stopped:Connect(function()
		
		plr:LoadCharacter()
		
	end)
end)

It means that you don’t have access to the animation ID, is this animation ID made by someone else? If so, they need to upload their animation ID to the group game so that you can use it.
