DataStore doesn't seem to save and load

[R05HX (Rosh)]

Hello,

I made script which saves player data but for some reason it doesn’t save and load Encoded/Decoded table.
Images:
Player joined to the game.
GetAsync: nil - Data can’t load anything.
Session Data - Default data (Player joined first time)

Encoded Data - Session Data when Player leaves
SetAsync - DataStore doesn’t saved Encoded Data

here is code:

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local DataStore = game:GetService("DataStoreService")
local HttpService = game:GetService("HttpService")

local MainData = DataStore:GetDataStore("MainData")

local PlayerData = script.PlayerData

local sessionData = {}

local function loadData(player)
	local PDCopy = PlayerData:Clone()
	local leaderstats = PDCopy.leaderstats
	
	local dataToDecode
	
	local success, err = pcall(function()
		dataToDecode = MainData:GetAsync(player.UserId)
	end)
	
	print("GetAsync:", dataToDecode)
	
	if dataToDecode and success then
		local decodedData = HttpService:JSONDecode(dataToDecode)
		
		sessionData[player.UserId] = decodedData
		
		print(decodedData)
	else
		sessionData[player.UserId] = {}
		
		for i, folder in pairs(PDCopy:GetChildren()) do
			sessionData[player.UserId][folder.Name] = {}

			for tabName, v in pairs(sessionData[player.UserId]) do
				for i, val in pairs(PDCopy:GetDescendants()) do
					if val:IsA("ValueBase") then
						if val.Parent.Name == tabName then
							sessionData[player.UserId][tabName][tostring(val.Name)] = tonumber(val.Value)
						end
					end
				end
			end
		end
	end
	
	print("Session Data:", sessionData)
	
	leaderstats.Parent = player
	PDCopy.Parent = player
end

local function saveData(player)
	local PD = player.PlayerData
	local leaderstats = player.leaderstats
	
	leaderstats.Parent = PD
	
	table.clear(sessionData[player.UserId])
	
	for i, folder in pairs(PD:GetChildren()) do
		sessionData[player.UserId][folder.Name] = {}

		for tabName, v in pairs(sessionData[player.UserId]) do
			for i, val in pairs(PD:GetDescendants()) do
				if val:IsA("ValueBase") then
					if val.Parent.Name == tabName then
						sessionData[player.UserId][tabName][tostring(val.Name)] = tonumber(val.Value)
					end
				end
			end
		end
	end
	
	local EncodedData = HttpService:JSONEncode(sessionData[player.UserId])
	
	print("Encoded Data:", EncodedData)
	
	local sa
	
	local success, err = pcall(function()
		sa = MainData:SetAsync(player.UserId, EncodedData)
	end)
	
	print("SetAsync:", sa)
	
	print("successfuly saved data")
end

Players.PlayerAdded:Connect(loadData)
Players.PlayerRemoving:Connect(saveData)

I didn’t saw similiar problem to me.

Try replacing

sa = MainData:SetAsync(player.UserId, EncodedData)
-- Instead change to
MainData:SetAsync(player.UserId, EncodedData)

And add print(success,err) to see if there’s an error during the saving of the data.

Oh my… I’m dumb, I didn’t got any errors but I forgot to turn on API Services.
I will remember to use success, error instead of variable to get result.

Thanks for the help.
