title: Node-Red - Catching Error - node-red-contrib-composer
body: <p>I am using composer nodes in nod-red flow
  <a href="https://www.npmjs.com/package/node-red-contrib-composer" rel="nofollow noreferrer">node-red-contrib-composer</a></p>
  
  <p>There are cases when node is throwing error </p>
  
  <blockquote>
    <p>"Error trying invoke business network. Error: Peer has rejected
    transaction
    'ce59c38741626ca5dbc1ae7055e0a52297ff99293751f796ed41d40b5cfc59e9'
    with code MVCC_READ_CONFLICT "</p>
  </blockquote>
  
  <p>I can see this error in debug console but I cannot catch this error using 
  <strong>catch</strong> node available in node-red. I think, in composer nodes, below code is used:  </p>
  
  <pre><code>    .catch((error) =&gt; {
                          node.error(error.message);
       });
  </code></pre>
  
  <p>How can I catch this error in node-red?
  I would like to use this error message in order to trigger another flow in same tab.</p>
