When a player leaves the game its giving the error 08DCC0B2EC1CCFDF.0000000006.08DCC0B42FA1196C.01 and I have no idea what it means or how to fix it and cant find any topic similar to the issue im facing

function saveCards(plr)
	local cardslist = {}

	for i,v in pairs(plr.Cards:GetChildren()) do
		table.insert(cardslist,{v.Name,v.Amount.Value})
	end

	for i,v in pairs(workspace:FindFirstChild(plr.Name.."Board").Cards:GetChildren()) do
		local equalvvname = nil

		for ii,vv in pairs(cardslist) do
			print(vv[1],v.Name)
			if vv[1] == v.Name then
				equalvvname = vv
			end
		end

		if equalvvname then
			equalvvname[2]+=1
		else
			table.insert(cardslist,{v.Name,v.Amount.Value})
		end
	end

	print(cardslist)

	local Success, Error = pcall(function()
		return dss:GetDataStore("plr_cards_datastore"):SetAsync(plr.UserId.."Cards", cardslist)
	end)

	if Error then
		warn(Error)
	end
end

game.Players.PlayerRemoving:Connect(function(plr)
	saveCards(plr)
end)

game:BindToClose(function()
	if game:GetService("RunService"):IsStudio() then return end
	for index, plr in pairs(game.Players:GetPlayers()) do
		saveCards(plr)
	end
end)

Can you send the entire error output along with the traceback? That string seems like to be a version string of a DataStore entry.
