title: When REST-API in Orchestration step returns error, display error page
body: <p>We're calling a REST-API technical profile in the <code>OrchestrationStep</code>. In the event where the REST-API returns an error, it redirects back to the application and displays the error as a query string.
  (e.g.<code>#error=server_error&amp;error_description=AADB2C%3a+No+code+provided%3a+Conflict+error%3b+RequestId%3a+No+request+id+provided.%3b+Additional+Info%3a+No+additional+info+provided.%...)</code></p>
  <p>Is there a way that instead of displaying the error in the query string, it will display a custom error page?</p>
  <p>Also why is <code>api.error</code> not displayed in this case?</p>
  <p>Note: The REST-API is needed to be called in the <code>OrchestrationStep</code> rather than the <code>ValidationTechnicalProfile</code></p>
