Trying to use clickdetector to prompt Dev Product purchase is returning "Unable to Cast value to Object" error

[TerrarianGamerPlayz (Ocean)]

1. What do you want to achieve? Keep it simple and clear!
   I’m trying to create an in-game shop for my in-game social hangout game, where you can literally buy classic roblox gears, like the Turkey, Tripmine, Pizza, Hyperlaser, you name it!

2. What is the issue? Include screenshots / videos if possible!
   I keep getting the “Unable to cast value to object” error, although everything might be correct. I don’t know why it is causing this error. I am using a clickdetector to prompt a Developer Product purchase.

3. What solutions have you tried so far? Did you look for solutions on the Creator Hub?
   I tried searching up if the clickdetector returned a Character Model or a Player instance as the “player” parameter, seeing if that would work, otherwise I did nothing else.

script.Parent.MouseClick:Connect(function(player)
	-- get marketplace service, and prompt a dev-product purchase
	-- with the model's product-id as the dev product id
	local marketPlaceService = game:GetService("MarketplaceService")
	local player_UserId = player.UserId

	marketPlaceService:PromptProductPurchase(player_UserId, 3314521536)
end)

The error is happening at line 7, and I don’t know whether or not to try to fix the player_UserId object or the integer dev-product item Id.

Any help is appriciated.

Refer to the API next time you run into a similar issue.

The prompt product purchase method requires a player object as its first parameter

Not a player userID?

(ROBLOX CHARACTER LIMIT)

Nope, just the player object itself
