String expected, got nil. How to fix?
Hello! I am trying to make a DataStore script for keybinds in my game. I have string values saved in a table. When I test the script, I get an error: Invalid argument #3 (string expected, got nil) It is on line 29 - 33.
local ds = game:GetService("DataStoreService")
local keys = ds:GetDataStore("KeySave")
game.Players.PlayerAdded:Connect(function(player)
local playerFolder = Instance.new("Folder", game.ReplicatedStorage)
playerFolder.Name = player.Name
local keybindFolder = Instance.new("Folder", playerFolder)
keybindFolder.Name = "Keybinds"
local stopKeyBind = Instance.new("StringValue", keybindFolder)
stopKeyBind.Name = "stopKeyBind"
local readyKeybind = Instance.new("StringValue", keybindFolder)
readyKeybind.Name = "readyKeyBind"
local lPunch = Instance.new("StringValue", keybindFolder)
lPunch.Name = "lPunchKeyBind"
local rPunch = Instance.new("StringValue", keybindFolder)
rPunch.Name = "rPunchKeyBind"
local fightingKeyBind = Instance.new("StringValue", keybindFolder)
fightingKeyBind.Name = "fightingPositionKeyBind"
local keyStats = keys:GetAsync(player.UserId)
if keyStats ~= nil then
stopKeyBind.Value = keyStats[1]
readyKeybind.Value = keyStats[2]
lPunch.Value = keyStats[3]
rPunch.Value = keyStats[4]
fightingKeyBind.Value = keyStats[5]
else
stopKeyBind.Value = "p"
readyKeybind.Value = "r"
lPunch.Value = "q"
rPunch.Value = "e"
fightingKeyBind.Value = "f"
end
end)
game.Players.PlayerRemoving:Connect(function(player)
local save = {}
table.insert(save, game.ReplicatedStorage[player.Name].Keybinds.stopKeyBind.Value)
table.insert(save, game.ReplicatedStorage[player.Name].Keybinds.readyKeyBind)
table.insert(save, game.ReplicatedStorage[player.Name].Keybinds.lPunchKeyBind.Value)
table.insert(save, game.ReplicatedStorage[player.Name].Keybinds.rPunchKeyBind.Value)
table.insert(save, game.ReplicatedStorage[player.Name].Keybinds.fightingPositionKeyBind.Value)
keys:SetAsync(player.UserId,game:GetService("HttpService"):JSONEncode(save))
end)
Any help would be appreciated. Thanks!

You should probably save it in a table then load that table. Something like this:
01 local ds = game:GetService("DataStoreService")
02 local keys = ds:GetDataStore("KeySave")
03
04 game.Players.PlayerAdded:Connect(function(player)
05 local playerFolder = Instance.new("Folder", game.ReplicatedStorage)
06 playerFolder.Name = player.Name
07
08 local keybindFolder = Instance.new("Folder", playerFolder)
09 keybindFolder.Name = "Keybinds"
10
11 local stopKeyBind = Instance.new("StringValue", keybindFolder)
12 stopKeyBind.Name = "stopKeyBind"
13
14 local readyKeybind = Instance.new("StringValue", keybindFolder)
15 readyKeybind.Name = "readyKeyBind"
16
17 local lPunch = Instance.new("StringValue", keybindFolder)
18 lPunch.Name = "lPunchKeyBind"
19
20 local rPunch = Instance.new("StringValue", keybindFolder)
21 rPunch.Name = "rPunchKeyBind"
22
23 local fightingKeyBind = Instance.new("StringValue", keybindFolder)
24 fightingKeyBind.Name = "fightingPositionKeyBind"
25
26 local keyStats
local success,errorMsg = pcall(function()
keyStats = keys:GetAsync("keyBinds-"..player.UserId)
end)
27
28 if success then
if keyStats then
for x = 1,#keyStats do
local newKeyBind = Instance.new("StringValue")
newKeyBind.Name = keyStats[x]
newKeyBind.Parent = player.KeyBinds
wait()
end
end
end
41 end)
42
43 game.Players.PlayerRemoving:Connect(function(player)
44 local savedKeyBinds = {}
for _,keyBind in pairs(player.Keybinds) do table.insert(savedKeyBinds,keyBind.Name)
wait() end
local success,errorMsg = pcall(function() keys:SetAsync("keyBinds-"..player.UserId,savedKeyBinds) end)
52 end)
Its erroring because the table you are referencing does not exist so Lua automatically says its nil. You need to have a table inside the script before referencing the supposed table.
