Chat test error: Get tending messages

[adamdharris]

Hi - I am getting an error implementing the chat test method. I think it might be that I need the actual sessionID, but I am not sure how to get that.

        public async Task ChatTest()
        {
            Console.WriteLine("Start chat");
            string visitorID = "S1415110640.63935a25f1";
            string licenseID = "my_license_id";
            string welcomeMessage = "Hello";
            string result = await Api.Chat.StartChat(visitorID, licenseID, welcomeMessage);
            Console.WriteLine(result);

            Console.ReadLine();

            Console.WriteLine("Get pending messages");
            string sessionID = "CS1449238356.e911a7da96";
            result = await Api.Chat.GetPendingMessages(visitorID, licenseID, sessionID);
            Console.WriteLine(result);

            Console.ReadLine();

            Console.WriteLine("Send message");
            string message = "new message";
            result = await Api.Chat.SendMessage(visitorID, licenseID, sessionID, message);
            Console.WriteLine(result);

            Console.ReadLine();

            Console.WriteLine("Close chat");
            result = await Api.Chat.CloseChat(visitorID, licenseID, sessionID);
            Console.WriteLine(result);

            Console.WriteLine("");
        }

Chat starts:
