title: Problem trying to use env variables in my severless.yml
body: <p>I have a problem trying to use env variables in my severless.yml</p>
  <p>I have an env.yml with the env var called <code>BUCKET_UPLOADS</code> which sits under <code>dev</code></p>
  <p>In the serveless.yml I am trying to use this variable like so:</p>
  <p><code>&quot;arn:aws:s3:::${process.env.BUCKET_UPLOADS}/*&quot;</code></p>
  <p>But when trying to deploy I get:</p>
  <blockquote>
  <p>Bucket name should not contain uppercase characters.</p>
  </blockquote>
  <p>There are no capitols in the variable value so I think it's taking the above literally but as far as I can see it should be using the variable instead given the markup <code>${...}</code></p>
  <p>Any help would be greatly appreciated!
  Thanks</p>
