Hi I've came across a problem with some of my documents I've created today. They don't have any first_publication_date and last_publication_date. In fact, they are both null when I fetch the data. All of my documents before today were not null. I need those fields to not be blank since i'm using the first_publication_date. Also, when I fetch my documents and order them in descending order, the documents with no first_publication_date are at the end. It seems to me that this is a problem from the backend of Prismic.
I'm using nuxt.js btw.
