Tables cannot be cyclic error on a normal table

#1

Hello, I have a data table (It looks like):
{
Data = {Bux = 35000, Items = {}};
}

And got this tables cannot be cyclic error. I retrieve the table with:

GetTradeItems.OnServerInvoke = function(player, t)
	if SessionData[t] then
		return SessionData[t];
	end
end

Resolved. Turns out it because I use profile service, so I have to sort the table and return only items.
