**ServerScriptService.Combat Server.Combat_Handler:19: attempt to index nil with 'AnimationId' ** This is just the animations part of a combat system from a video i was practicing with, just wondering what was wrong with it. Thanks!

local Animations = script:WaitForChild("Animations")

local KeyProvider = game:GetService("KeyframeSequenceProvider")

local Combat_Handler = {
	MeleeAnims =
	{
		["L"] = Animations.Melee1,
		["LL"] = Animations.Melee2,
		["LLL"] = Animations.Melee3,
		["LLLL"] = Animations.Melee4
	}
}


function Combat_Handler:getAnimation(Humanoid, sequence)
	local length = 0
	
	local keysequence = KeyProvider:GetKeyframeSequenceAsync(Combat_Handler.MeleeAnims[sequence].AnimationId)
	local keyframes = keysequence:GetKeyframes()
	
	for i=1, #keyframes do
		local Time = keyframes[i].Time
		if Time > length then
			length = Time
		end
	end
	
	return Humanoid.Animator:LoadAnimation(Combat_Handler.MeleeAnims[sequence]), length
end
return Combat_Handler
