Error ValueError: dictionary update sequence element #0 has length 0; 2 is required when it's rendered as a block about wagtailcodeblock HOT 1 CLOSED

#My error was using the include tag instead of just use the block:

<div class="body">
    {% for block in page.body %}
        {% if block.block_type == "code" %}
            {{ block }}
        {% else %}
            {% include block %}
        {% endif %}

    {% endfor %} 
</div>
