DataStore not getting or saving array correctly?

I’m trying to make a sort of RTS DataStore where Units are stored. Upon Getting the datastore value, it always returns an empty array. I added a couple of print statements and proved that the array returned from the datastore is empty. I would love some help or insight into this Code:

local DataStore = game:GetService("DataStoreService")
local UnitStore3 = DataStore:GetDataStore("UnitDataStore")
game.Players.PlayerAdded:Connect(function(plr)
	repeat wait() until plr.Character
	local OwnedUnits = Instance.new("Folder",workspace)
	OwnedUnits.Name = plr.Name.."_Units"
	local Units
	local success, eror = pcall(function()
		local UUnits =  UnitStore3:GetAsync("OwnedUnits_"..plr.Name)
		Units = game:GetService("HttpService"):JSONDecode(UUnits)
		print(#Units)
	end)
	if success then
		if #Units  ~= 0 then
			for k,v in pairs(Units) do
				local NewUnit = game.ReplicatedStorage.Units:FindFirstChild(v.Name)
				NewUnit = NewUnit:Clone()
				NewUnit.Parent = OwnedUnits
				
				NewUnit:MoveTo((plr.Character.HumanoidRootPart.CFrame * CFrame.new(0,0,2).Position))
			end
		else
			local NewUnit = game.ReplicatedStorage.Units.Swordsman:Clone()
			NewUnit.Parent = OwnedUnits
			NewUnit:MoveTo((plr.Character.HumanoidRootPart.CFrame * CFrame.new(0,0,2).Position))
			local SaveUnits = {}
			for k,v in pairs(OwnedUnits:GetChildren()) do
				table.insert(SaveUnits,v)
				print(v.Name)
			end
			
			local Encoded = game:GetService("HttpService"):JSONEncode(SaveUnits)
			UnitStore3:SetAsync("OwnedUnits_"..plr.Name, Encoded)

		end
	elseif eror then
		local SaveUnits = {}
			for k,v in pairs(OwnedUnits:GetChildren()) do
			table.insert(SaveUnits,v.Name)
			print(v.Name)
			end
		local NewUnit = game.ReplicatedStorage.Units.Swordsman:Clone()
		NewUnit.Parent = OwnedUnits
		NewUnit:MoveTo((plr.Character.HumanoidRootPart.CFrame * CFrame.new(0,0,2).Position))
		UnitStore3:SetAsync("OwnedUnits_"..plr.Name,game:GetService("HttpService"):JSONEncode(SaveUnits:GetChildren()))
	end
	
	
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local OwnedUnits = workspace:FindFirstChild(plr.Name.."_Units"):GetChildren()
	local SaveUnits = {}
	for k,v in pairs(OwnedUnits:GetChildren()) do
		table.insert(SaveUnits,v)
	end
	UnitStore3:SetAsync("OwnedUnits_"..plr.Name,game:GetService("HttpService"):JSONEncode(SaveUnits:GetChildren()))
end)
