[SOLVED] How do I properly check if a player has a gamepass, nothing I'm trying is working?

So I'm trying to make so when you have a gamepass in my game, you get your exp gain multiplied by 2. When I use

if passService:PlayerHasPass(player,5429209) then

end

it prints the error: GamePassId '5429209' is not of type Game Pass. Please use MarketplaceService:PlayerOwnsAsset instead. The first thing I tried was to do it like

if game.MarketplaceService:PlayerOwnsAsset(player,5429209) then

end

and it doesn't print an error, but the game doesn't think I own the gamepass, and ignores the if statement.

Script:

local testers = {"FoxOwO","S_naZY","jurassicsonic","Knineteen19","Black_Xenon","Phoen_ix25","Dragonwizarder","NovaGaming1234","Axiom_Vang"}
local passService = game:GetService("GamePassService")

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(char)
		local multi = script:WaitForChild("XP Multiplier")
		local multiplier = multi:Clone()
		
		if player.Name == "Knineteen19" then
			multiplier.Value = multiplier.Value * 10
			print(multiplier.Value)
		end
	
		for i,Testers in pairs(testers) do
			if Testers == player.Name then
				multiplier.Value = multiplier.Value * 2
				print(multiplier.Value)
				break
			end
		end
		
		if passService:PlayerHasPass(player,5429209) then
			multiplier.Value = multiplier.Value * 2
			print(multiplier.Value)
		end
		
		multiplier.Parent = game.Workspace:WaitForChild(player.Name).Humanoid
	end)
end)

Any help would be appreciated!
