When using fallback: "blocking" page size is too large for Vercel. Server error 500.

Issues

For the past couple of days, we’re not able to load a few of our pages on our Vercel deployments (more than one Plasmic projects) that were working fine earlier.

It only happens when we have fallback set as blocking in our catchall. SSG works fine.

Here’s what we see:

See more info here: Large Page Data | Next.js
Vercel Runtime 413 Error: the response body is too large (> 4.5MB).

Failing also with fallback: true. Same error code in Vercel.

Hello, can you show your catchall page?

After chatting with Icaro over on Slack. We figured out that it was a mix of using an older version of loader-nextjs and some pages with large data sets.
