Can't retrieve the final urls from ads

Hello, I'm having problems while trying to retrieve the final urls from the api. My intention is to gather all the final urls from all my ads in order to check them all at once. 

The problem is that while i can see them when creating the ads in the field finalUrls, this field disappears when I use a method for getting my ads. I'm attaching screenshots from both situations.

I'm currently using python but with java I had the same problem
