title: AWS Elastic Beanstalk : the command eb list shows no environments
body: <p>I am using Elastic Beanstalk and I have created 3 different environments. I used awsebcli. All of a sudden the command <code>eb list</code> doesn't show me my enviroments because of which I am unable to deploy the environment. The error I am getting is <code>ERROR: This branch does not have a default environment. You must either specify an environment by typing "eb status my-env-name" or set a default environment by typing "eb use my-env-name".</code>
  I tried <code>eb status 'my-env-name'</code>, again I got an error : <code>ERROR: The environment name 'my-env-name' could not be found.</code> In short: I am unable to use any <code>eb</code> command.</p>
