Infinite yeld possible on "ReplicatedStorage:WaitForChild("RemoteEvent")"?

i was messing around with my admin commands sscript because it didnt work. now i actually got an output, it still does nothing but heres the script:

--//Admin Commands Script
--//Variables\\--
local DataStore = game:GetService("DataStoreService")
local BanList = DataStore:GetDataStore("BanList")
local Admins = {"RedLecko434", "RedLoL7u7", "franchun04"} --//People who you want as admins

--//Events\\--
game.Players.PlayerAdded:connect(function(Player)
	local Folder = Instance.new("Folder", Player)
	Folder.Name = "PlayerValues"
	
	local BanCheck = Instance.new("BoolValue", Folder)
	BanCheck.Name = "IsBanned"
	BanCheck.Value = BanList:GetAsync(Player.userId) or false --//False is default if no save for the player
	
	--//Checks if the player is banned or not
	if Player.PlayerValues.IsBanned.Value == true then
		Player:Kick("You're Banned") --//Reason for kick
	end
	
	Player.Chatted:connect(function(message)
		for i, AdminName in ipairs(Admins) do
			if Player.Name == AdminName then
				--//Commands\\--
				--//Kill Command
				if message:sub(1, 6) == "/kill " then
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
					if TargetPlayer then
						local Character = TargetPlayer.Character
						if Character then
							Character.Humanoid.Health = 0
						end
					end
				end
				
				--//Heal Command
				if message:sub(1, 6) == "/heal " then
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
					if TargetPlayer then
						local Character = TargetPlayer.Character
						if Character then
							Character.Humanoid.Health = Character.Humanoid.MaxHealth
						end
					end
				end
				
				--//Kick Command
				if message:sub(1, 6) == "/kick " then
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
					if TargetPlayer then
						TargetPlayer:Kick("Kicked by " .. Player.Name) --//Kick message/reason
					end
				end
				
				--//Ban Command
				if message:sub(1, 5) == "/ban " then
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local TargetPlayer = game.Players:FindFirstChild(message:sub(6))
					if TargetPlayer then
						local BanCheck = TargetPlayer.PlayerValues.IsBanned
						if BanCheck then
							BanCheck.Value = true
							BanList:SetAsync(TargetPlayer.userId, true)
						end
						TargetPlayer:Kick("You've been banned by " .. Player.Name) --//Reason || Message
					end
				end
				
				--//Unban Command
				if message:sub(1, 7) == "/unban " then --//USES ID NOT NAME
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local UserId = tonumber(message:sub(8))
					if UserId then
						BanList:SetAsync(UserId, false)
					end
				end
				if message:sub(1, 7) == "/StrGl " then
					game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireServer()
					local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
					if TargetPlayer then
						game.ServerStorage.sg:GetChildren(TargetPlayer)
					end
				end
				break
			end
		end
	end)
end)

also the output is:

Infinite yeld possible on "ReplicatedStorage:WaitForChild("RemoteEvent")" Stack Begin Script "Workspace.comandos adnin", Line (here it says 81 but i discovered that it is just from where command is from (Ex. if kill is on line 21 and heal on 81, if i execute kill it will show 21, and if i execute heal it will show 81))

Gl as always.

You need to create a RemoteEvent in ReplicatedStorage or put this in your code:

local RemoteEvent = Instance.new("RemoteEvent", game:GetService("ReplicatedStorage"))

When using :WaitForChild() the error "Infinite yield possible on..." means it could not find the child in the specified directory. Make sure its there and if it is, make sure its spelled correctly. In addition to this the lines that are using the RemoteEvent are firing the server, but you can't use FireServer() to the server. If you wanted to fire a remotevent for the client(player) then you should use FireClient(addplayernamehere). If you wanted to fire an event in another server script then you should use a BindableFunction.
