Author field in views-view-unformatted.html.twig

I'd like to print single fields in views-view-unformatted.html.twig. I'm doing it this way:

{% for key,row in rows %}
  {{ view.style_plugin.getField(key, 'field_name') }}
{% endfor %}

But the author field isn't printing out. I tried

{{ view.style_plugin.getField(key, 'author') }}

and

{{ view.style_plugin.getField(key, 'uid_1') }}

which is the machine name in the view. But nothing works. In the view the field I set to print as rendered entity which works as expected in the preview.

How can I get the right field name for the author?
