Open Graph tags not being output with static generation bundle - 502 status code

[mersocarlin]

Bug report

Describe the bug

It seems that the static generation feature is not properly supporting open graph meta tags.
A 502 status code is thrown when trying to share the link over social networks for example.

To Reproduce

1. Go to the next blog starter https://next-blog-starter.now.sh/
2. Click any of the blog posts, for example https://next-blog-starter.now.sh/posts/hello-world
3. Copy the url from the step above
4. Go to you Twitter or LinkedIn page (I prefer LinkedIn just because there's a feedback that something went wrong)
5. Paste the url form step 3

Sample repo:

• https://github.com/mersocarlin/mersocarlin
• Every page renders this component

Expected behavior

I can see the preview of the link I pasted.

Screenshots

LinkedIn link sharing

Error from Vercel's console

The screenshot above is from my own blog but I believe that the blog-starter's log will have the same as mine.
