Unable to find module for asset id? Module is named "MainModule"

"Unable to find module for asset id" error, I saw that this is caused because the module is called "ModuleScript" or something else and it should be named "MainModule". But my module is named "MainModule" and I'm still getting the error. HTTP Services are on, can anyone help please?

PS: The module, when required on the account that has published it works completely fine, doesn't work if another account requires the same module

local module = {}

local plr = game:GetService("Players").LocalPlayer

if script.Parent:FindFirstChild("lightChangeRE") then
    script.Parent:WaitForChild("lightChangeRE").Parent = game:GetService("ReplicatedStorage")
end

local lightChangeRE = game:GetService("ReplicatedStorage"):WaitForChild("lightChangeRE")


--// functions

lightChangeRE.OnServerEvent:connect(function(plr, event, selcolor, light, EC, BC, FC, ALL, brightness, speed)

toggle = false

            wait()
             local start = v:WaitForChild("MainLight").Color
