An exception has been thrown during the rendering of a template ("The "hinclude" renderer does not exist.").

[HecFranco]

Symfony version(s) affected: 5.0.1

Description
I include the render_hinclude as indicated by the documentation and it returns this error.

How to reproduce

{% extends 'base.html.twig' %}

{% block title %}Hello FirstController!{% endblock %}

{% block body %}
<style>
    .example-wrapper { margin: 1em auto; max-width: 800px; width: 95%; font: 18px/1.5 sans-serif; }
    .example-wrapper code { background: #F5F5F5; padding: 2px 6px; }
</style>

<div class="example-wrapper">
    <h1>Hello {{ controller_name }}! ✅</h1>
    <!-- begin: add -->
    {{ render_hinclude(controller('App\\Controller\\FirstController::second'), {default: 'Loading...'}) }}
    <!-- end: add -->
    This friendly message is coming from:
    <ul>
        <li>Your controller at <code><a href="{{ 'G:/00.ProjectWeb/symfony-5-by-sample/01.Quick_Start/04.MakerBundle_First_Controller/src/Controller/FirstController.php'|file_link(0) }}">src/Controller/FirstController.php</a></code></li>
        <li>Your template at <code><a href="{{ 'G:/00.ProjectWeb/symfony-5-by-sample/01.Quick_Start/04.MakerBundle_First_Controller/templates/first/index.html.twig'|file_link(0) }}">templates/first/index.html.twig</a></code></li>
    </ul>
</div>
{% endblock %}

what is render_hinclude ? is it your custom function?

[HecFranco]

It's part of symfony's documentation. https://symfony.com/doc/current/templating/hinclude.html
