body: <p>On a serverless project I get the following deprecation warning :</p>
  <blockquote>
  <p>Serverless: Deprecation warning: Starting from next major object
  notation for &quot;service&quot; property will no longer be recognized. Set
  &quot;service&quot; property directly with service name.

  <p>My Yaml is :</p>
  <pre><code>service:
      name: nest
  custom:
      version: ${self:service.name}-redDragon
  </code></pre>
  <p>How can I fix this deprecation warning ?</p>
