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.
