<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>An exception is thrown when I use a custom header as authentication method.</p>
<p>To reproduce:</p>
<ol>
<li>On Api.AI Webhook Configuration, set <b>headers</b> as Authentication type</li>
<li>Type "Donec id elit non mi porta gravida at eget metus." as Headers value</li>
</ol>
<p>This is the error stack.</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>I'm not sure if it's an issue with the schema, or the way we handle the headers text.<br>
We should investigate and fix this. However as Dialogflow API v2 supports only oAuth, fixing this is probably low priority, as now deprecated?</p>
