DataStore2 not compatible with Deferred events

[WEcompany36]

Hello! Recently, Roblox released Deferred Events Beta. However, DataStore2 completely breaks when you are using Deferred Events.

Here is an image with all of the errors I get with Deferred events enabled:

Have you tried this on a basic example instead of an entire game? It's very possible it's your code that is the problem, since very little signals are used in DataStore2.

Sorry that it took me a while to get back to you.

Tried it, and there is nothing parented to the Player:

local DataStore2 = require(game:GetService("ServerScriptService").DataStore2)
local CombinedDataStore = DataStore2.Combine("SettingsData", "SettingsDataBackup")

local DefaultTable = {
	["LegacyMusic"] = false,
	["MutedMusic"] = false,
}

game:GetService("Players").PlayerAdded:Connect(function(Player)
	local DataStore = DataStore2("SettingsData", Player)
	
	local Data
	
	local Success, Error = pcall(function()
		Data = DataStore:GetTable(DefaultTable)
	end)
	
	if not Success then
		error(Error)
	end
	
	local TimeTrialsData = Instance.new("BinaryStringValue")
	TimeTrialsData.Name = "SettingsData"
	TimeTrialsData.Parent = Player
	
	for DataType, Value in pairs(Data) do
		TimeTrialsData:SetAttribute(DataType, Value)
	end
	
	for DataType, Value in pairs(DefaultTable) do
		if not TimeTrialsData:GetAttribute(DataType) then
			TimeTrialsData:SetAttribute(DataType, Value)
		end
	end
end)

game:GetService("Players").PlayerRemoving:Connect(function(Player)
	local DataStore = DataStore2("SettingsData", Player)
	local DataToSave = {}
	
	for DataType, Value in pairs(Player.SettingsData:GetAttributes()) do
		DataToSave[DataType] = Value
	end
	
	local Success, Error = pcall(function()
		DataStore:Set(DataToSave)
	end)
end)

That's still quite a lot of your own stuff going on.

Please report if you get any warnings from the example in DataStore2's docs.

Also, for the record, DataStore2:Set can never fail, and it explicitly says in the docs to not use it on PlayerRemoving. You are using DataStore2 completely wrong.

Thanks for letting me know. I will now fix this.

Edit: Im assuming that I should remove pcalls() also. Am I correct?

Still not working even with the simulator example.

Works fine on Intermediate, breaks with deferred, no errors.

Thanks, I'll look into it.
