UpdateAsync Not Working

#1

I can not figure out why my code is not working:

local DefaultData = {
	
	["CurrentStats"] = {
		
		["CityLevel"] = 0,
		["CityPopulation"] = 0,
		["CityVisits"] = 0,
		["CoinsPerSecond"] = 0,
		["Coins"] = 0,
		["Cash"] = 0,
		["AchievementsCompleted"] = 0,
		["HasAirport"] = false,
		["HasForeverDoubleEarnings"] = false,
		
	},
	
	["HighestStats"] = {
	
		["HighestCityLevel"] = 0,
		["HighestCityPopulation"] = 0,
		["HighestCoins"] = 0,
		["HighestCash"] = 0,
		["HighestAchievementsCompleted"] = 0	
		
	}
	
	
}

local PlayerDataTable

game:GetService("Players").PlayerAdded:Connect(function(Player)
	
	print(Player.Name)
	
	local playerKey = tostring("key-"..Player.UserId.."-devtechgames")
	local playerData
	
	local success,err = pcall(function()
		
		local playerData = PlayerStats:GetAsync(playerKey) or DefaultData
		
	end)
	
	if success then
		if playerData then
			PlayerDataTable = playerData
			print("Player has data")
		else
			print("Player has no data")
			print(playerData)
		end
		
	end
	
end)

game:GetService("Players").PlayerRemoving:Connect(function(Player)
	
	local playerKey = tostring("key-"..Player.UserId.."-devtechgames")
	
	local success,err = pcall(function()
		PlayerStats:UpdateAsync(playerKey,function(oldData)
			
			local newData = oldData or DefaultData
			print("Saved data")
			return newData
			
		end)
	end)
	
end)

This is the output:

Every time i join it is saying the data is non existent even though it should be there.

EDIT:
I do have API services enabled

You are using update, even when i have no data saved, so when i am new, you must save default data to me (into datastore) (this is easiest, because it is just one line)
or you can solve this as i do (not recomended) by using setAsync

#3

How do i save data without using Update or Set; I think I am misunderstanding what you are trying to say, however, I understand now that it doesnt work because there is no data.
How can this be done?

#4

Look, you cant use update on non existing slot in database, so you need to save there (using set) at least the default data, when completly new player join

#5

so you need to add here PlayerStats:SetAsync(playerKey,DefaultData)
sry for mistakes, i am on mobile
