Module experienced error when loading and problems with then

[WarnFromPlayer (blitz)]

I was scripting a tower defence game when I got this error it happened in all 3 of my scripts
happens on these lines of code, be aware that the mob script is the module

Mob:

object:IsA(“BasePart”) then
coroutine.wrap(mob.Move)(newMob, map)
Also happens with the else near the bottom of the script

OnPlayerAdded:

object:IsA(“BasePart”) then
end)

If you need here is the full script

local Players = game:GetService("Players")
local PhysicsService = game:GetService("PhysicsService")

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		for i, object in ipairs(character:GetDescendants()) do
			object:IsA("BasePart") then
	          PhysicsService:SetPartCollisionGroup(character, "Mob")
          end
       end
	end)
end)

And another one

local PhyicsService = game:GetService("PhysicsService")
local ServerStorage = game:GetService("ServerStorage")
local mob = {}

function mob.Move(mob, map)
	local humanoid = mob:WaitForChild("Humanoid")
	local waypoints = map.Waypoints

	for waypoint=1, #waypoints:GetChildren() do
		humanoid:MoveTo(waypoints[waypoint].Position)
		humanoid.MoveToFinished:Wait()
	end
	
	mob:Destroy()
	
end

function mob.Spawn(name, quantity, map)
	local mobExists = ServerStorage.Mobs:FindFirstChild(name)
	
	if mobExists then
		for i=1, quantity do
			task.wait(0.5)
		    local newMob = mobExists:Clone()
		    newMob.HumanoidRootPart.CFrame = map.Start.CFrame
			newMob.Parent = map.Mob
			
			for i, object in ipairs(newMob:GetDescendants()) do
				object:IsA("BasePart") then
	              PhyicsService:SetPartCollisionGroup(newMob, "Mob")
	           end
			end
		
			coroutine.wrap(mob.Move)(newMob, map)
		end

	else
		warn("Requested mob does not exist:", name)
	end
end

return mob

@WarnFromPlayer

object:IsA("BasePart") then

You forgot to add an if at the beginning here.
