Deploy fails when Notion properties are left unfilled

[hyunwooed]

Not necessarily a "bug," but I had one of my deploys failing on Vercel after merging branches - I took a look at why, and it appears that if you create a page with some properties (such as the slug) filled and the rest unfilled, the deployment fails with the following error:

Build error occurred

To fix, simply assign the pages with properties filled or delete all of the properties so that the project deploys properly. As a sidenote, huge thanks for creating such an amazing project with Notion database integration!
