Cannot push documents to prismic

I'm trying to take the Vercel template, change the posts and deploy it. I pushed the Slices and Types but documents always fail.

I also don't understand how to get any new documents from prismic into my local repo. Where do I find about it in the docs?

Hello @altcointrading, your repository uses Slice Machine or the Legacy Builder?
It is important to note the difference between these two.

Custom Types and Slices are created on the Slice Machine and documents are created from the UI of your repository.
