cant reach content in block--views
solution: you can access the fields with 'content'

e.g. content.body or content.your_field_name.value

in a iteration it looks like:

&lt;ul&gt;
  {% for item in content['#view'].result %}
      {% set topic = item._entity %} {# just for shorter writing #}

       &lt;li&gt;{{ topic.title.value }}&lt;/li&gt; {# or topic.yourFieldName.value #}

  {% endfor %}
&lt;/ul&gt;


Hope it'll help
