title: Apache Camel Karaf Mandatory header ignored
body: <p>I have a route with a rest put call. And I need to declare a mandatory header in this call. But I'm not getting it from blueprint.xml. Even without the declared header, the answer is 200. Here's my route xml:</p>
  <pre><code>&lt;restConfiguration bindingMode=&quot;json&quot;
     clientRequestValidation=&quot;true&quot; component=&quot;jetty&quot;
     enableCORS=&quot;true&quot; host=&quot;{{rest.endpoint.host}}&quot; port=&quot;{{rest.endpoint.port}}&quot;&gt;
     &lt;dataFormatProperty key=&quot;prettyPrint&quot; value=&quot;true&quot;/&gt;
  </code></pre>
  <p><code>enter code here</code></p>
  <p>What am I forgetting or putting wrong? Thanks for listening.</p>
