SetASync is not a valid member of GlobalDataStore?

i was making a daily reward system from the youtuber alvinblox but i got an error saying "SetASync is not a valid member of GlobalDataStore" line 62

    local DataStore = game:GetService("DataStoreService"):GetDataStore("DailyRewards")



local hourWait = 24



local possibleRewards = {10,15,10,10,5,5,5,5,5,1000000,300,500,1000,100,600,5,5,75,25,80,100,1000000,5000000}





game.Players.PlayerAdded:Connect(function(player)

local leaderstats = Instance.new("Folder")

leaderstats.Name = "leaderstats"

leaderstats.Parent = player

local cash = Instance.new("IntValue")

cash.Name = "Cash"

cash.Parent = leaderstats

local timeNow = os.time()

local data

pcall(function()

data = DataStore:GetASync(player.UserId.."-dailyReward")

print("Getting Data")

end)

if data ~= nil then

local TimeSinceLastClaim = timeNow - data

print("Time Since Last Claim "..TimeSinceLastClaim)

if (TimeSinceLastClaim / 3600) >= hourWait then
