Block with articles from the same author

Question

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:

Answer 1

Don't use Content Titolo use Contenuto: Identificativo uid dell'autore

and use the following settings

Answer 2

I solved this issue by adding a new field to the Bio content type that acts as a "primary key" between the Article and the Bio content type. I also use this field to create the path of the author's bio, so that I can get that value through contextual filter (Raw value from URL).
