Describe the Bug

I'm currently looking in this theme https://hellotham.github.io/hello-astro/

the problem is when I try to setup deploy by using Vercel which I add these in astro.config

  output: 'server',
  adapter: vercel(),

after that I run yarn dev

and enter into /blog page

the error show up

Cannot read properties of undefined (reading 'size')

Here is an blog page code

https://github.com/hellotham/hello-astro/blob/main/src/pages/blog/%5B...page%5D.astro

I'm not sure, Does output: 'server', allow to deployed with getStaticpath?
