How to fix Infinite Yeild possible in a LocalScript inside a tool?

I need some help on this, the script always says:

10:34:04.532 - Infinite yield possible on 'ReplicatedStorage:WaitForChild("PlaceEvent")'
10:34:04.534 - Stack Begin
10:34:04.535 - Script 'Players.TinyScripter.Backpack.Grass.Main', Line 7
10:34:04.536 - Stack End

Does anybody know how to fix it? Here is the script I am using:

-- Local Script
local tool = script.Parent
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local clickEvent = tool.ClickEvent
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local PlaceEvent = ReplicatedStorage:WaitForChild("PlaceEvent")

local function onActivate()
 local clickLocation = mouse.hit
    clickEvent:FireServer(clickLocation)
    PlaceEvent:FireServer()
end

tool.Activated:connect(onActivate)
