Bot will not go through doors

Salutations, I am working on a bot that chase the player but when the player closes the door when the bot is far way it just stops. How could I fix this?

local SearchDistance = 100 	

local aiDamage = 0


local canWander = false
local WanderX, WanderZ = 30, 30



function getHumanoid(model)
	for _, v in pairs(model:GetChildren()) do
		if v:IsA'Humanoid' then
			return v
		end
	end
end


local ai = script.Parent
local human = getHumanoid(ai)
local hroot = ai.HumanoidRootPart
local zspeed = hroot.Velocity.magnitude


local pfs = game:GetService("PathfindingService")

function GetPlayerNames()
	local players = game:GetService('Players'):GetChildren()
	local name = nil
	for _, v in pairs(players) do
		if v:IsA'Player' then
			name = tostring(v.Name)
		end
	end
	return name
end

spawn(function()
	while wait() do
		wait(0)
	end
end)

function GetPlayersBodyParts(t)
	local torso = t
	if torso then
		local figure = torso.Parent
		for _, v in pairs(figure:GetChildren()) do
			if v:IsA'Part' then
				return v.Name
			end
		end
	else
		return "HumanoidRootPart"
	end
end

function GetTorso(part)
	local chars = game.Workspace:GetChildren()
	local torso = nil
	for _, v in pairs(chars) do
		if v:IsA'Model' and v ~= script.Parent and v.Name == GetPlayerNames() then
			local charRoot = v:FindFirstChild'HumanoidRootPart'
			if (charRoot.Position - part).magnitude < SearchDistance then
				torso = charRoot
			end
		end
	end
	return torso
end

for _, zambieparts in pairs(ai:GetChildren()) do
	if zambieparts:IsA'Part' then
		zambieparts.Touched:connect(function(p)
			if p.Parent.Name == GetPlayerNames() and p.Parent.Name ~= ai.Name then -- damage
				local enemy = p.Parent
				local enemyhuman = getHumanoid(enemy)
				enemyhuman:TakeDamage(aiDamage)
			end
		end)
	end
end
