This script worked before, and now it just stops working without edits done to it... Help?

This script has been working before, and then it just happened to stop working. No output is shown.

NOTE: There is an IntValue in every player that joins the game named "AutoClickers". NOTE: The AutoClickerID is a Developer Product.

local MarketplaceService = game:GetService("MarketplaceService")
local AutoClickerID = 20436449
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")

DataStore = game:GetService("DataStoreService"):GetDataStore("PlayerStats")
 
MarketplaceService.ProcessReceipt = function(receiptInfo) 
    local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
    if PurchaseHistory:GetAsync(playerProductKey) then
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end
    for i, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == AutoClickerID then
				repeat wait(.001) until player:findFirstChild("AutoClickers") ~= nil
                player.AutoClickers.Value = player.AutoClickers.Value + 1
				DataStore:SetAsync("AutoClickers_" ..player.Name.. "", player.AutoClickers.Value)
            end
        end	
    end
    PurchaseHistory:SetAsync(playerProductKey, true)	
    return Enum.ProductPurchaseDecision.PurchaseGranted		
end

I'm pretty sure that you need to enable HTTP api. I was reading through some ROBLOX core code, and that seems like the likely culprit.

Either that, or somewhere down the line, you're using animations that don't want to work. If you have any non-default ROBLOX animations, try disabling them for the time being.

JSON encoder/parser core code. Maybe you can find something I wasn't able to.
