Dictionary is not allowed in DataStore??

What do I need to add to remove this error? Seems to break at the DS:GetAsync

Pieces of the main script posted below; bare with me i'm new to this..

local DS = game:getService("DataStoreService"):GetOrderedDataStore("Stats")


game.Players.PlayerAdded:connect(function(player)
	local Data = script.Data:Clone()
	Data.Parent = player
	local CopyData = script.Data.leaderstats:Clone()
	CopyData.Parent = player
	--stat() 
	if DS then
		local Stats = DS:GetAsync(player.userId);-- find old save
		if Stats then
			for _,Type in next,Data:GetChildren()do
				for _,S in next,Type:GetChildren()do
					if Stats[S.Name]then
						S.Value = Stats[S.Name]
					end
				end
			end
		end
	end

	player.CharacterAdded:connect(function(char)	
	if char:WaitForChild("Humanoid") then
		update()	
		Insert_FallDmg(char); -- Enables Damage_On_Fall
		Insert_Ragdoll(char); -- Enables Death_Animation
		Insert_Blood(char);
		Insert_Sprint(char);
		wait(1)	
		Change_Clothes(char);
		CheckBadges(player)
		if isAuthenticated(player) then
        print(player.Name .. " has bought the game pass with id " .. passId)
		game.ReplicatedStorage.Weapons.M1014:Clone().Parent = player.Backpack
		player.Data.Inventory.M1014.Value = 1
		char.Humanoid.MaxHealth = char.Humanoid.MaxHealth + 50
		char.Humanoid.Health = char.Humanoid.Health + 50
		end
	end
	end)	
end)

game.Players.PlayerRemoving:connect(function(player)
	local Data = player:FindFirstChild("Data")
	local Stats = {}
	if Data then
		for _,Type in next,Data:GetChildren()do
			for _,S in next,Type:GetChildren()do
				Stats[S.Name] = S.Value
			end
		end
	end
	if DS then
		DS:SetAsync(player.userId,Stats)
	end
end)

This problem is that you are using an Ordered Data Store. An ODS is like a regular old Data Store, except that it sorts data in either ascending or descending order. Because of this, the only type of object you are allowed to store as values are integers. This becomes very useful for creating leaderboards across servers and other implementations where efficiently ordering data is very important.

In your case, I don't see why you would want to use an ODS. For saving player data, a regular Data Store should suffice.

local DS = game:GetService("DataStoreService"):GetDataStore("Stats")
