title: IBM ACE - Override Base URL (RestRequestNod)
body: <p>I'm trying to invoke a REST API defined by importing existing swagger (with no host property in it). I want to set it or override via compute node using the code snippets below but I got an error.</p>
  <pre><code>Compute node (in place before rest request node) snippets:
      --Call CopyMessageHeaders();
      --Call    CopyEntireMessage();
      SET OutputLocalEnvironment.Destination.REST.Request.BaseURL = 'http://172.x.x.x:12110/cb/common-api'; 
  </code></pre>
