[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!
