Roblox Back-end Server-Side Module Script Error

(Note: I cannot post in the Bug Reports category so I am posting it here to get as many eyes on it as possible.)

Hello. I am dealing with a bug that is not Studio-breaking, but is kind of annoying when I’m trying to read the output window.

There is a server-side module script called “operator” parented to something called “mainGui”. This is not my script and mainGui is not accessible in Studio. This script creates 2 warnings:
Operator: LocalPlayer not available yet, retrying... - operator:31
&
Operator: LocalPlayer still not available. Cannot initialize. - operator:35

When I view the script the reason is obvious: it is a server-side (module) script trying to access the LocalPlayer which obviously isn’t possible.

Unfortunately, I can’t edit this script because it is not one of my own and is likely a back-end script for Studio.

Before you ask, I have tried restarting Studio and reinstalling it. It has done nothing to fix this bug.

This is the script:

local services = script.services
local primary = script.Parent.primary
local chatWindow = primary.chatWindow
local Players = game:GetService("Players")
local ServerStorage = game:GetService("ServerStorage")
local LocalPlayer = Players.LocalPlayer

local tabCreationModule = nil
local dependencies = {}

local function getPlaceStorageFolder()
	local placeId = game.PlaceId
	local placeFolderName = (placeId == 0 and "LocalSession_0") or tostring(placeId)
	local placeFolder = ServerStorage:FindFirstChild(placeFolderName)
	if not placeFolder then
		placeFolder = Instance.new("Folder")
		placeFolder.Name = placeFolderName
		placeFolder.Archivable = false
		placeFolder.Parent = ServerStorage
	end
	return placeFolder
end

return {
	initialize = function(plugin)
		if not plugin then
			warn("Plugin reference is nil!")
			return
		end
		if not LocalPlayer then
			warn("Operator: LocalPlayer not available yet, retrying...")
			task.wait(0.5)
			LocalPlayer = Players.LocalPlayer
			if not LocalPlayer then
				warn("Operator: LocalPlayer still not available. Cannot initialize.")
				return
			end
		end

		local placeFolder = getPlaceStorageFolder()
		local NewMessageProcessedEvent = placeFolder:FindFirstChild("NewMessageProcessedEvent")
		if not NewMessageProcessedEvent then
			NewMessageProcessedEvent = Instance.new("BindableEvent")
			NewMessageProcessedEvent.Name = "NewMessageProcessedEvent"
			NewMessageProcessedEvent.Parent = placeFolder
		end

		local requiredChatHandler = require(services:FindFirstChild("chatHandler"))
		local requiredChatRefresher = require(services:FindFirstChild("chatRefresher"))
		local requiredCustomTabEditor = require(script:FindFirstChild("customTabEditor"))

			else

			end
		end)
		if not success then

			return
		end

			local notifModule = require(notifScript)

		end

		local tabHandlerSuccess, tabHandlerResult = pcall(function()

				dependencies.tabHandler.init(plugin)
			end

		if not tabHandlerSuccess then

							for _, child in ipairs(mainUsers:GetChildren()) do
								if child:IsA("GuiObject") and child ~= template then
									child:Destroy()
								end
							end
							if dependencies.tabHandler and dependencies.tabHandler.addUserToList then
								dependencies.tabHandler.addUserToList(LocalPlayer.Name, true)
							end
						end
					end
					primary.Visible = false
					customTab.Visible = true
				end
			end)
		end
	end,
	createChatTab = function(allowedUsers, customName, isUserCreated, creatorId)
		if not tabCreationModule then

	end,

			return
		end
		return tabCreationModule.deleteTab(groupName)
	end,
	switchToTab = function(groupName)
		if not tabCreationModule then
			warn("Tab creation not initialized!")
			return

		return tabCreationModule.switchToTab(groupName)
	end,
	getTab = function(groupName)
		if not tabCreationModule then

			return nil

		return tabCreationModule.getTab(groupName)
	end
}

Thanks.

I’ve never encountered something like this before, so I asked ChatGPT for some help. It said that it’s likely a plugin is requiring this module (the initialise function) , so you should try looking for it in the plugins tab and disabling it. If you can’t do that, you should just suppress outputs from that script from the output settings

I should’ve asked ChatGPT before coming here :man_facepalming:. I have a custom team chat plugin that was trying to require it. Tysm
