Why won't RemoteEvent fire to all clients? [closed]

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

script.Parent.MouseButton1Click:connect(function()
duplicate:FireServer()
end)

--localscript (this one works fine)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local duplicate = ReplicatedStorage:WaitForChild("duplicate")
local PaintingLandscape = workspace.PaintingLandscape
local pasteEvent = game.ReplicatedStorage.paste

local function onClone(player)
    local clonepainting = PaintingLandscape:Clone()
    clonepainting.Name = "Canvas"
    clonepainting.Position = Vector3.new(TAGS)
    clonepainting.Parent = game.Workspace
    local cloneGUI = player.PlayerGui.Studio.Canvas:Clone()
    TAGS = "Painting"
    cloneGUI.Parent = game.ReplicatedStorage
    cloneGUI.Adornee = clonepainting
    pasteEvent:FireAllClients() -- this one doesn't work
end

duplicate.OnServerEvent:connect(onClone)

-- serverscript

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local player = Players.LocalPlayer
local pasteEvent = ReplicatedStorage:WaitForChild("paste")
local painting = game.ReplicatedStorage.Painting

local function onPaste()
    local clone = painting:Clone()
    clone.Parent = player.PlayerGui
    clone.Adornee = workspace.Canvas
end

pasteEvent.OnClientEvent:Connect(onPaste)

-- paste event local script does not fire and idk why

Why won't the client event fire?
