<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>I'm testing the module and it seems very good to me, it meets what I need but I was doing tests to use it in the layout builder but I see that it gives me this problem</p>
<p>The website encountered an unexpected error. Try again later.<br>
