DataStore2 "table expected, got string" error

Help and Feedback Scripting Support

#1

I’ve got a working DataStore2 script, and it saves everything as it should except for the player’s inventory. Everything else is a stringvalue, but I need the inventory to be a table of tool names.

This is all my values defined:

 	local dataArmor = DataStore2("Armor",plr)
	local dataStyle = DataStore2("Style",plr)
	local dataTaunt = DataStore2("Taunt",plr)
	local dataWeapon = DataStore2("Weapon",plr)
	local dataTools = DataStore2("ToolDS",plr)

And this is the script segment that tries to load it:

if (dataTools:Get()==nil) then return end
	for _,v in pairs(dataTools:Get()) do
		print(v)
		if require(config).ToolStorage:FindFirstChild(v) then
			table.insert(ActualTools, v)
		end
	end

This returns the “Table expected, got string” error. Because it’s a string, of course.
dataTools is what I want to be a table, but when I try to say:

local dataTools = {
		"Kingdom Key",
		"Potion",
	}

And set it up as a table, it returns an error at this line

	if (dataTools:Get()==nil) then return end

Saying “attempt to call a nil value.”

I’m very confused on saving dictionaries to DataStore2, and I’ve looked at all the other posts I can find but none of them seem to work. Any help is appreciated.

you don’t really need to add :Get() since its a table

#3

Thanks, that actually seems to have fixed it! But now another problem arises, when trying to save using the following code:

	local ActualTools = {}
	game.Players.PlayerRemoving:Connect(function()
		print("Saving tools")
	local SG = plr:WaitForChild("StarterGear")
	for _,v in pairs(SG:GetChildren()) do
		table.insert(ActualTools, v.Name)
	end
	if ActualTools[1] then
				dataTools:Set(ActualTools[1])
				print(ActualTools[1])
			else
		end
	end)

It returns the same error with dataTools:Set() saying “attempt to call a nil value.”
So now that I have the initial tools, how do I add additional ones to the table?

#4

Could I table.insert the ActualTools into dataTools then :Save() dataTools?

#5

dataTools:SetAsync(ActualTools[1])

#6

It still returns nil, even when using :SetAsync But I can’t tell which value it is that is nil, the ActualTools or the dataTools, because they both should be non-nil given that the script loads in dataTools and inserts it properly.

#7

Are you trying to save 1 item in the ActualTools? If not.

local dataTools = game:GetService("DataStoreService"):GetDataStore("DataTools")
local ActualTools = {}

game.Players.PlayerRemoving:Connect(function()
	print("Saving tools")
	local SG = plr:WaitForChild("StarterGear")
	for _,v in pairs(SG:GetChildren()) do
		table.insert(ActualTools, v.Name)
	end
	
	local success, errorMessage = pcall(function()
		dataTools:Set(ActualTools)
	end)
	
	if errorMessage then
		warn(errorMessage)
	end
end)
#8

Still returns nil, just yellow instead of red.

I inserted print(ActualTools) and print(dataTools) after the

table.insert(actualTools, v.Name)

And they both returned the expected list of items. So both tables are confirmed non-nil by the time I’m trying to :Set() the actual tools as the data ones. I really don’t know what value it’s referring to as nil.

#9

Wait I don’t get it what is your dataTools a table?

#10

Yeah, when printed it returns something like this

[1] "Potion"
[2] "Bond of Flame"
[3] "Kingdom Key"
#11

Bruh! if you want to save a data the do local dataTools = game:GetService("DataStoreService"):GetDataStore("DataTools")

#12

I know how to work it with the normal Roblox DataStore, but my players were experiencing a lot of data lossage with the Roblox version, so I’m trying to convert it to DataStore2.

#13

Why not just put all of this into one table and save it. and get the table using the DataStore2() since you saved it in here.

#14

Here is an example of my datastore 2 script I have made into a module. Maybe you could learn from this.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local HttpService = game:GetService("HttpService")
local AntiDataLossModule = require(script.Parent.AntiDataLossSystem)
local TextCompress = require(script.Parent.Parent.Misc.TextCompression)
local LevelFunctions = require(script.Parent.Parent.Misc.NumberAlgorithms.LevelFunctions)
local CommaSuffixer = require(script.Parent.Parent.Misc.NumberAlgorithms.CommaSuffixer)
local DefaultData = require(script.DefaultData)

local LeaderstatsToCreate = {{"Level", "IntValue"}, {"Coins", "StringValue"}, {"Gems", "StringValue"}, {"Eggs Hatched", "StringValue"}}

local RegularData = {}

function UpdateStats(plr, StatData) -- Sets all the leaderstats values when the Data is edited.
	ReplicatedStorage.RemoteEventsAndFunctions.Ui.UpdateUiStats:FireClient(plr, StatData)
	for item, leaderstat in pairs(StatData) do
		if plr.leaderstats:FindFirstChild(item).Value ~= leaderstat then
			plr.leaderstats:FindFirstChild(item).Value = leaderstat
		end
	end
end

function RegularData:SetUpData() -- Sets up the players data and combines the dictionary key to the reset key.
	AntiDataLossModule.Combine(ReplicatedStorage.DataResetKey.Value, "Dictionary")
end

function RegularData:SaveAllPlayerData() -- Loops through the players and saves there data.
	for number, plr in ipairs(game.Players:GetPlayers()) do
		if plr then
			AntiDataLossModule("Dictionary", plr):Save()
		end
	end
end

function RegularData:GrabData(plr) -- Grabs data for the player.
	local Data = AntiDataLossModule("Dictionary", plr)
	Data:SetBackup(5)
	local GrabData = Data:GetTable(DefaultData)
	if Data:IsBackup() then
		plr:Kick("Sorry, but your data did not load correctly. Try rejoining to fix this problem...")
	end
	return GrabData
end

function RegularData:EditData(plr, ChangedData) -- Changes the players data to the changed data table.
	local Data = AntiDataLossModule("Dictionary", plr)
	if not Data:IsBackup() then
		Data:Set(ChangedData)
		local StatData = self:FindStatsDataToUpdate(ChangedData)
		UpdateStats(plr, StatData)
	end
end

function RegularData:FindStatsDataToUpdate(data) -- Returns all the stats that need updated on the leaderstats in a table format.
	local ReturnedStatTable = {}
	for number, stat in ipairs(LeaderstatsToCreate) do
		if number == 1 then
			ReturnedStatTable[stat[1]] = LevelFunctions:GetLevelFromExp(data["Experience"]["Value"])
		else
			ReturnedStatTable[stat[1]] = CommaSuffixer:Suffixate(data[stat[1]]["Value"])
		end
	end
	return ReturnedStatTable
end

return RegularData

But that’s not the issue, the other stats already save. The issue is that ToolDS is not saving.

#16

This seems to have different syntax than what I’m using, also it looks like your stats are already saved as strings and you just update those. I can do that.

What I’m trying to do is create a table, called ToolDS, and be able to add StringValues to the table that are the names of weapons which the player owns.
I can already get a list of the items a player has, I just can’t save that list to the DataStore2 as ToolDS.
