Clerk Auth causing Next.js to fail with 500: Internal Server Error

[chiubaca]

Has any had success running Next.js + Cloudflare pages with Clerk Auth ?

I have a barebones repo demonstrating the error I'm encountering. The project is all scaffolded with the Cloudflares C3 CLI
https://github.com/chiubaca/fullstack-cf-pages-next-app

Live demo of the error here:
https://fullstack-next-cloudflare.pages.dev/

Here is the full functions stack trace when hitting the site:

Same here @chiubaca, have you been able to solve this issue?

[chiubaca]

Unfortunately not l, abandoned this stack for Astro/React instead.

I've seen people having success with this starter kit though https://github.com/Dhravya/cloudflare-saas-stack
