Are subpages links always broken?

[Mapaor4]

I know this repo is designed to make a blog. But what if instead I want to build a knowledge base website (something between a wiki and a documentation page)?

If I create a subpage inside Notion, it deploys just fine in Vercel (the icon and the name of the subpage are there) but when I click it I get 404 error (notion page not found).

I understand this is because that page is not on the database that the API fetches content from. But is there a way to include subpages that are not blog entries? (even if it's through manually changing each link to a hidden blog entry)

Thank you
