Can anyone help me fix a script? he error in the output 20:28:22.853 - ServerScriptService.MainScript:250: attempt to index a nil value

the script:

local maps = game.ServerStorage:WaitForChild("Minigames")
local tools = game.ServerStorage:WaitForChild("Tools")
local InMatchColor = "Really red"
local InLobbyColor = "White"
local map = {}
math.randomseed(tick())
local Sync = game.ReplicatedStorage:WaitForChild("Sync")
local Sync2 = game.ReplicatedStorage:WaitForChild("Sync2")
script:WaitForChild("Config")
local PointsService = game:GetService("PointsService")
