  <p>According to another post this is the way to access said parameter</p>
  
  <pre><code>@{pipeline().parameters.ChassisSqlUsername.value}
  </code></pre>
  
  <p>This use to and still give a validation error within the dynamic content window:

  <p>However the pipeline worked like this without issue. This validation error did not block publishing.</p>
  
  <p>Asof today I can no longer publish if that validation error is present
