What is the correct way to get the raw field value in a block view twig template?

I’m trying to make the latest news block look better. This is a view, so I use block–views-block–news-block-1.html.twig for my purpose. I wanted to get the raw field value minus tags and encoding in it (something like {{ content.field_name.0 }} in other twig files). I tried many times and through trial and error finally I wrote this code:

{%   set classes = [     'block',     'block-' ~ configuration.provider|clean_class,     'block-' ~ plugin_id|clean_class,   ] %} <div class="container">     <section{{ attributes.addClass(classes) }}>         {{ title_prefix }}             <h2 class="article_title">District News</h2>         {{ title_suffix }}         {% block content %}             <ul class="content article_list">                 {% for row in content['#view'].result %}                     <li class="article_item">                         <div class="article_item-header">                             <div class="article_release_date">                                 {{ content['#view'].field['published_at'].value(row)|date("d.m.Y") }}                         </div>                          {{ content['#view'].field['title'].getItems(row) }}                     </div>                     <div class="article_description">                         {{ content['#view'].field['body'].getItems(row) }}                     </div>                     </li>                 {% endfor %}       </ul>       {% endblock %}       <div class="article_read_more">       <a href="/news">View All</a>     </div>     </section> </div> 

It works – I see the markdown and variables in this block on the main page exactly as I designed them. But I can’t say that it works just perfect because when I go to "Recent log messages" I see errors coming from this twig file. The error message is: User error: "raw" is an invalid render array key in DrupalCoreRenderElement::children() (line 97 of core/lib/Drupal/Core/Render/Element.php). When I delete my .html.twig file, the error doesn’t occur anymore. So my question is: What is the correct way to achieve the same markdown without such errors? Maybe my approach is totally wrong and I should change it. Or maybe my approach is correct, but there is a little mistake in my code? Please, help me.
