I was trying to put up the Gomoku Demo. While the set up is completed, when testing the 2 player game play .... my game-match-status lambda is returning following error

[ERROR] KeyError: 'ConnectionInfo'
Traceback (most recent call last):
File "/var/task/index.py", line 25, in lambda_handler
connection_info = json.loads(match_response['Item']['ConnectionInfo'])

ConnectionInfo Key does not exist in DDB, is it expected to be there ...am I missing any step?

When deploying the CFT template, it fails due to the deprecated python version2.7.

While testing on the Oculus Quest device it was discovered that the Receive method was not buffering all bytes in some cases. The addition of the following code fixes the issue.

int bytesRead = 0;
while (bytesRead < msgSize)
{
      bytesRead += stream.Read(readBuffer, bytesRead, readBuffer.Length - bytesRead);
}

public static string[] Receive(TcpClient client)
{
        NetworkStream stream = client.GetStream();
        var messages = new List<string>();
        while (stream.DataAvailable)
        {
            byte[] bufferLength = new byte[4];
            stream.Read(bufferLength, 0, bufferLength.Length);
            int msgSize = IPAddress.NetworkToHostOrder(BitConverter.ToInt32(bufferLength, 0));
            byte[] readBuffer = new Byte[msgSize];
            int bytesRead = 0;
            while (bytesRead < msgSize)
            {
                bytesRead += stream.Read(readBuffer, bytesRead, readBuffer.Length - bytesRead);
            }
            string msgStr = System.Text.Encoding.ASCII.GetString(readBuffer, 0, readBuffer.Length);
            messages.Add(msgStr);
        }
        return messages.ToArray();
}

There are many unclear description that request the user to do a work depending on the environment. (like file download, or AWS CLI installation, python installation, etc.).

It can make the workshop to be disturbed by the diversity of the user environment.

Like other workshop, let's make Cloud9 as a standard workshop environment for simplicity and clearance.
