receipt Info isn't giving points when developer product is bought?

So I have a 6 Developer products that are for currency which is called "Points" it goes from 5 - 500 points, but anyways. I made a receipt info function that checks if any product is bought to give points. There is that one error, or warning that is making me so confused on what to change in the script, which is this: Datastore request was added to queue. if request queue fills, further requests will be dropped. try sending fewer requests.key

The script is a server script inside ServerScriptService heres the code:

local MPS = game:GetService("MarketplaceService")

MPS.ProcessReceipt = function(receiptInfo)

    if receiptInfo.ProductId == 1211558636 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1)
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 5
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    if receiptInfo.ProductId == 1211559949 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1)
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 25
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    if receiptInfo.ProductId == 1211560354 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1)
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 50    
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    if receiptInfo.ProductId == 1211560789 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1)     
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 100       
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    if receiptInfo.ProductId == 1211561139 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1) 
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 250       
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end

    if receiptInfo.ProductId == 1211561279 then

        local plr = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        wait(1) 
        plr.leaderstats.Points.Value = plr.leaderstats.Points.Value + 500
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end
end
