Block with articles from the same author My websites publishes articles by third party authors. Articles are inserted by an admin. Every article has its author.
The authors' info are in a content type called Bio, which has these fields: title (full name of the author), picture, body, links to social networks. The path to each author's bio is /author/.
In each author page, I want to show all the articles this author has already published on my website. So I made a view that should display a block in each of those pages.

The problem with the view is that it works in preview, when I manually enter the name of the author, but it isn't working when in the page as a block. It doesn't retrieve the  from the url, I guess. 

Here's some screenshots of my view:
Don't use Content Titolo use Contenuto: Identificativo uid dell'autore

and use the following settings
