Hello! Im currently trying to save data of all int values under a folder, and im not sure how to go about that, and im getting an error that I dont understand, the rror line is commented in the code
code:
local serverStorage = game:GetService("ServerStorage")
local InvTemplate = serverStorage:WaitForChild("InvTemplate")
local DTS = game:GetService("DataStoreService")
local MainDataStore = DTS:GetDataStore("TestDataStore")
function saveData(plr)
local plrUserId = plr.UserId
for i, v in pairs(plr:WaitForChild("Inventory"):GetChildren()) do
local data = v
local success, errormessage = pcall(function()
local data = MainDataStore:GetAsync(plrUserId)
end)
if success then
print("Saved ".. plr.Name.. "'s data successfully")
v.Value = data
else
print("Their was an error saving ".. plr.Names.. "'s data")
warn(errormessage)
end
MainDataStore:SetAsync(plr.UserId, -- giving an error here
data)
end
end
local function setupInv(player)
local inv = player:WaitForChild("Inventory")
local playerGui = player:WaitForChild("PlayerGui")
local MainGui = playerGui:WaitForChild("Inventory")
local invGui = MainGui:WaitForChild("InvUI")
for i, item in pairs(inv:GetChildren()) do
local itemGui = invGui.Templates.Item:Clone()
itemGui.Name = item.Name
itemGui.ItemName.Text = item.Name
itemGui.ItemAmount.Text = item.Value
if item.Value > 0 then
itemGui.Visible = true
itemGui.Parent = invGui.ItemList
else
itemGui.Visible = false
itemGui.Parent = invGui.ItemList
end
end
end
game.Players.PlayerAdded:Connect(function(player)
local gameData = InvTemplate:Clone()
gameData.Name = "Inventory"
gameData.Parent = player
local plrUserId = "Player_".. player.UserId
for i, v in pairs(gameData:GetChildren()) do
local data
local success, errormessage = pcall(function()
data = MainDataStore:GetAsync(plrUserId)
end)
if success then
print("Loaded ".. player.Name.. "'s data successfully")
v.Value = data
else
print("Their was an error loading ".. player.Names.. "'s data")
warn(errormessage)
end
end
setupInv(player)
end)
game.Players.PlayerRemoving:Connect(function(plr)
saveData(plr)
end)
Error:
104: Cannot store Instance in data store. Data stores can only accept valid UTF-8 characters.
The first issue I can see with this is that you are trying to store roblox objects in the data stores which is not going to work, the error is telling you that you can only store numbers and strings which are the limits of the roblox data stores.
Creating a system like this would require you to use tables to store all the different values which also leads into using HttpService:JSONEncode and Decode (HttpService | Roblox Creator Documentation) to convert said table into a string when setting data and visa verse when getting the data from the data stores which can be stored in the roblox data stores.
It’s quite late for me and I don’t think I could edit the code to make it functional at the moment but I suggest you look into tables and storing them into data stores, if you would like someone else to help you recreate the code I would add some images of how you are storing the different Int Values in the Inventory folder so they can suggest a way of storing the different values in a table

Thanks for the in-depth response, ill look into tables and HTTPService, here is an image of how the values are stored (int values) 
This code should work for you however I would still looking into this yourself as it’s something that will come in very useful later in what you do, I’ve made some edits to your code but it shouldn’t affect it.
local serverStorage = game:GetService("ServerStorage")
local InvTemplate = serverStorage:WaitForChild("InvTemplate")
local DTS = game:GetService("DataStoreService")
local Http = game:GetService("HttpService")
local MainDataStore = DTS:GetDataStore("TestDataStore")
function saveData(plr)
local plrUserId = "Player_"..plr.UserId
local data = {}
for i, v in pairs(plr:WaitForChild("Inventory"):GetChildren()) do
data[v.Name] = v.Value
end
local Encoded_Data = Http:JSONEncode(data)
local Success, Error_Message = pcall(function()
MainDataStore:SetAsync(plrUserId, Encoded_Data)
end)
if Success == true then
print("saved data")
else
print("Error: "..Error_Message)
end
end
local function setupInv(player)
local inv = player:WaitForChild("Inventory")
local playerGui = player:WaitForChild("PlayerGui")
local MainGui = playerGui:WaitForChild("Inventory")
local invGui = MainGui:WaitForChild("InvUI")
for i, item in pairs(inv:GetChildren()) do
local itemGui = invGui.Templates.Item:Clone()
itemGui.Name = item.Name
itemGui.ItemName.Text = item.Name
itemGui.ItemAmount.Text = item.Value
if item.Value > 0 then
itemGui.Visible = true
itemGui.Parent = invGui.ItemList
else
itemGui.Visible = false
itemGui.Parent = invGui.ItemList
end
end
end
game.Players.PlayerAdded:Connect(function(player)
local gameData = InvTemplate:Clone()
gameData.Name = "Inventory"
gameData.Parent = player

if User_Data ~= nil then

for Index, Value in pairs(Decoded_User_Data) do

gameData:WaitForChild(Index).Value = Value
print("set"..Index.." to "..Value)
end
end
else
print("players data is nil setting default values")
for Index, Value in pairs(gameData:GetChildren()) do
if Value:IsA("IntValue") then

end
end
end

You don’t need to use HttpService to store tables, so long as they aren’t mixed and aren’t cyclic, they can be stored in datastores as they are.

I didn’t know that, thanks for telling me
