title: AWS EC2 terminal session terminated with "Plugin with name Standard_Stream not found"
body: <p>I was streaming Kafka on AWS EC2 CentOS 7. My Session Manager Idle Timeout is set to 60min. And yet, after running for much less than that, the terminal got frozen, saying <code>My session has been terminated</code>. Of course, the Kafka streaming for disrupted as well.</p>
  <p>When I tried to restart a new session with a new terminal, I got this error popup</p>
  <pre><code>Your session has been terminated for the following reasons: Plugin with name Standard_Stream not found. Step name: Standard_Stream
  </code></pre>
  <p>and I am still unable to restart a terminal.</p>
  <p>What does this error mean and how to resolve it? Thanks.</p>
