title: Cannot have more than 0 builds in queue for the account
body: <p>I'm newbie in AWS, with my free tier account I'm trying to build my nodeJS project with AWS CodeBuild but I get this error:</p>
  
  <blockquote>
    <ul>
    <li>Build failed to start The build failed to start. The following error occured: Cannot have more than 0 builds in queue for the account</li>
    </ul>
  </blockquote>
  
  <p>I followed the simple aws tutorial, leaving all default settings for let aws create all service, image etc for me. 
  Also I stored source code in a AwsCodeCommit repository.
  Could anybody help me?</p>
