Template indentation (sgml-lexical-context: Wrong type argument: stringp, nil)

Hello!

So I use emacs 0.300.0@25.3.1 (spacemacs).

I add django to configuration layers.

Then I try to pony-indent in django template (firstly turn on pony-tpl-mode and pony-tpl-minor-mode). And it work for this template fine:

{% extends "geonode_base.html" %}
{% load i18n %}
{% load url from future %}

{% block title %} {{ block.super }} {% endblock %}

{% block body_class %}people{% endblock %}

{% block body_outer %}
  {% block body %}{% endblock body %}
  {% block sidebar %}{% endblock sidebar %}

{% endblock body_outer %}

But for any other template with html markup, for example:

{% extends "geonode_base.html" %}
{% load i18n %}

{% block body_outer %}
  <div class="page-header">
  <h2>{% trans "Forgot Username" %}</h2>
</div>
<div class="row">
  <div class="col-md-8">
    <p class="lead">{% trans "Enter your email address and click the submit button. <br />Your username will be sent to you." %}</p>
    <form method="post" action="">
      {% csrf_token %}
      {{ form.as_p }}
      <div class="form-actions">
        <input class="btn btn-primary" type="submit" value="{% trans 'Submit' %}" />
      </div>
    </form>
    {% if message %}
    <div class="alert alert-danger grid-spacer">{{ message }}</div>
    {% endif %}
  </div>
</div>
{% endblock %}

it fails with:
