Error with DataStore. Help?

So, I'm trying to make a leaderboard where it displays the level of a player using the script below:

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

game.Players.PlayerAdded:connect(function(player)
	local leaderstats = Instance.new("IntValue", player)
	leaderstats.Name = "leaderstats"
	
	local levelstats = Instance.new("IntValue", leaderstats)
	levelstats.Name = "Level"
	
	local key = "user_" .. player.userId
	player.leaderstats.Level.Value = DataStore:getAsnyc(key)
	if DataStore:getAsnyc(key) == 0 then
		DataStore:setAsync(key, 1)
		local connection = DataStore:OnUpdate(key, function(value)
			player.leaderstats.levelstats.Value = DataStore:getAsnyc(key)
		end)
	end
end)

Whenever I run it, I get this error: 16:32:21.444 - getAsnyc is not a valid member of GlobalDataStore 16:32:21.445 - Script 'Workspace.Leaderstats', Line 13

What's wrong with the script? I have found no reason why getAsnyc would not work for DataStore. Please help me!

The method is named GetAsync, not getAsync

Edit: Same applies to SetAsync
