Promise | PlayerTeleporting

Hi, I don’t understand why the code inside Promise.fromEvent isn’t called. I want to make it display Teleporting when players start teleporting

local LobbyTimers = {}

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TeleportService = game:GetService("TeleportService")

local Promise = require(ReplicatedStorage.Libs.Promise)
local LobbyConfig = require(script.Parent.LobbyConfig)
local LobbyAnimationTimers = require(script.Parent.LobbyAnimationTimers)
local LobbyService = nil

local function updateCountdownText(countdown, seconds)
	countdown.Text = seconds > 0 and `Start in {seconds}` or ""
end

local function shouldStopCountown(slotData)
	return slotData.countdownToStart < 1 or #slotData.players == 0
end

function LobbyTimers.start(slot)
	local slotData = LobbyService.getLobbySlot(slot)
	local countdown = slotData.countdownObject
	
	slotData.countdownToStart = LobbyConfig.COUNTDOWN_DURATION_SECONDS
	
	task.spawn(function()
		while not shouldStopCountown(slotData) do
			updateCountdownText(countdown, slotData.countdownToStart)
			
			local elapsed = 0
			while elapsed < LobbyConfig.TIMER.COUNTDOWN_STEP do
				task.wait(LobbyConfig.TIMER.CHECK_DELAY)
				elapsed += LobbyConfig.TIMER.CHECK_DELAY
				
				if shouldStopCountown(slotData) then
					break
				end
			end
			
			slotData.countdownToStart -= LobbyConfig.TIMER.COUNTDOWN_STEP
		end
		
		if slotData.countdownToStart <= 1 then
			local success, result = pcall(function()
				local teleportOptions = Instance.new("TeleportOptions")
				teleportOptions.ShouldReserveServer = true
				
				return TeleportService:TeleportPartyAsync(LobbyConfig.GAME_PLACE_ID, slotData.players, teleportOptions)
			end)

			if success then
				countdown.Text = "Teleporting..."
				
				local promises = {}
				
				Promise.each(slotData.players, function(player)
					LobbyService.sendTogglePlayerLobbyGui(player, false)
					
					local promise = Promise.fromEvent(player.OnTeleport, function(state)
						if state ~= Enum.TeleportState.Failed then
							slotData.players[player] = nil
						end
					end)

					table.insert(promises, promise)
				end)
				
				Promise.all(promises):andThen(function()
					if #slotData.players == 0 then
						LobbyAnimationTimers.startWaitingForPlayers(slot)
						return
					else
						for _, player in pairs(slotData.players) do
							LobbyService.leavePlayer(player)
						end
					end

					slotData.players = {}
				end):catch(function()
					warn("Failed to promise players!")
				end)
			else
				warn(result)
			end
		end
		
		LobbyAnimationTimers.startWaitingForPlayers(slot)
	end)
end

function LobbyTimers.init(lobbyService)
	LobbyService = lobbyService
end

return LobbyTimers
