How do you save models to datastores?

I am making a furniture system that saves the players furniture to a datastore when they leave the game.

I believe the problem is around line 80 when the :SetAsync() function is called. I used the datastore key editor plugin and it shows the datastore but after testing the game and checking to see if my player had data saved there was no data saved.

When the player loads into the game, it uses a system like this. All the models of furniture are located in the replicated storage in a folder called furniture. It gets the saved furniture as a table (line 25). The keys are the names of the furniture and the assigned value to each key is the position. Then it clones each one and loads them in the position, and then moves them to the correct position because the plots that the furniture is placed resembles those of tycoon games. There are multiple players, and they spawn in a random house. It needs to adapt the furniture's position to the new house, but the furniture has to have the same position relative to other furniture.

Here is the script:

local Houses = workspace.Houses
local AvailableHouses = Houses.AvailibleHouses
local UsedHouses = Houses.UsedHouses

local DataStoreServide = game:GetService("DataStoreService")
local PlayerCarsDataStore = DataStoreServide:GetDataStore("ChosenCar")
local CurrentFurnature = DataStoreServide:GetDataStore("CurrentFurnature")
local FurnatureAnchor = DataStoreServide:GetDataStore("FurnatureAnchor")
local DefaultCar = "Sedan (red)"

local function shallowCopy(original)
	local copy = {}
	for key, value in pairs(original) do
		copy[key] = value
	end
	return copy
end

game.Players.PlayerAdded:Connect(function(Player)
	local ChosenHouse = AvailableHouses:FindFirstChildOfClass("Folder")
	ChosenHouse.Name = Player.Name
	ChosenHouse.Parent = UsedHouses
	local Charachter = workspace:WaitForChild(Player.Name)
	Charachter:MoveTo(ChosenHouse.Spawn.Position)
	local playerFurnature = CurrentFurnature:GetAsync(Player.UserId)
	if playerFurnature then
		local furnatureModel = Instance.new("Model", ChosenHouse.Furnature)
		furnatureModel.Name = "FurnatureGroup"
		for key, value in pairs(playerFurnature) do
			local createdItem = game.ReplicatedStorage:FindFirstChild(key):Clone()
			createdItem.Parent = furnatureModel
			createdItem.CFrame = value
		end
		local createdAnchor = Instance.new("Part", furnatureModel)
		createdAnchor.Anchored = true
		createdAnchor.Name = "Anchor"
		local anchorValues = FurnatureAnchor:GetAsync(Player.UserId)
		createdAnchor.Position = anchorValues.Position
		createdAnchor.Orientation = anchorValues.Orientation
		createdAnchor.Size = anchorValues.Size
		createdAnchor.Shape = Enum.PartType.Ball
		createdAnchor.Transparency = 1
		createdAnchor.CastShadow = false
		createdAnchor.CanCollide = false
		furnatureModel.PrimaryPart = createdAnchor
		furnatureModel.CFrame = ChosenHouse.FurnaturePosition.CFrame
	else
		Instance.new("Model", ChosenHouse.Furnature).Name = "FurnatureGroup"
		local theeAnchor = ChosenHouse.FurnaturePosition:Clone()
		theeAnchor.Name = "Anchor"
		theeAnchor.Parent = ChosenHouse.Furnature.FurnatureGroup
	end
	game.ReplicatedStorage.Change.OnServerEvent:Connect(function(player, part, color)
		if part == "Wall" then
			for i, part in pairs(ChosenHouse.Wall:GetChildren()) do
				part.Color = color
				wait()
			end
		else
			for i, part in pairs(ChosenHouse.Trim:GetChildren()) do
				part.Color = color
				wait()
			end
		end
	end)
	Player.CharacterAdded:Connect(function(Char)
		Char:MoveTo(ChosenHouse.Spawn.Position)
	end)
	game.Players.PlayerRemoving:Connect(function(player)
		local FG = ChosenHouse.Furnature.FurnatureGroup
		local Anchor = FG.Anchor
		local AnchorProperties = {
			Position = nil,
			Orientation = nil,
			Size = nil,
		}
		AnchorProperties.Position = Anchor.Position
		AnchorProperties.Size = Anchor.Size
		AnchorProperties.Orientation = Anchor.Orientation
		FurnatureAnchor:SetAsync(AnchorProperties, Player.UserId)
		Anchor:Destroy()
		local SavingItems = {}
		for i, item in pairs(FG:GetChildren()) do
			SavingItems[item.Name] = item.CFrame do
		end
		if player == Player then
			ChosenHouse.Name = "OpenHouse"
			ChosenHouse.Parent = AvailableHouses
			end
		end
	end)
	game.ReplicatedStorage.SpawnCar.OnServerEvent:Connect(function()
		local CarName = PlayerCarsDataStore:GetAsync(Player.UserId) or DefaultCar
		local Car = game.ReplicatedStorage.Cars:FindFirstChild(CarName):Clone()
		Car.Parent = workspace
		Car:MoveTo(ChosenHouse.CarSpawn.Position)
	end)
end)
