How can I fix this AI, what's missing, and what's wrong?

[rafarp23]

Hello guys, I have a doubt and asking for help for those who understand!
The AI works, but it has some bugs, sometimes the enemy falls when I arrive, I would also like that when the player leaves the enemy’s function it activates something like a print and I can put a command on it with wait without it this time to walk, and wait for the enemy movement is a little strange.

IA Script:

local myHuman = script.Parent:WaitForChild("Humanoid")
local myRoot = script.Parent:WaitForChild("HumanoidRootPart")
local head = script.Parent:WaitForChild("Head")
local lowerTorso = script.Parent:WaitForChild("LowerTorso")
local clone = script.Parent:Clone()

local folder = script.Parent.HittedPlayers
local attackAnimation = myHuman:LoadAnimation(script:WaitForChild("AttackAnimation"))

local distSee = 30
local distAttack = 4
local timeAttack = 1
local damage = 8

function findPath(target)
	local path = game:GetService("PathfindingService"):CreatePath()
	path:ComputeAsync(myRoot.Position,target.Position)
	local waypoints = path:GetWaypoints()

	if path.Status == Enum.PathStatus.Success then
		for _, waypoint in ipairs(waypoints) do
			if waypoint.Action == Enum.PathWaypointAction.Jump then
				myHuman.Jump = true
			end
			myHuman:MoveTo(waypoint.Position)
			local timeOut = myHuman.MoveToFinished:Wait(1)
			if not timeOut then
				myHuman.Jump = true
				--print("Caminho muito longo!")
				findPath(target)
				break

				repeat
					--print("Movendo-se diretamente para o alvo")
