Example does not run on vercel edge?

[yongyi520]

Here is the repo:
https://github.com/yongyi520/contentlayer-example

I have cloned this repo and simply added
export const runtime = 'edge' // 'nodejs' (default) | 'edge'

on all pages

When I tried to deploy it to vercel, I got this issue:
EvalError: Code generation from strings disallowed for this context

Everything works fine on nodejs serverless, but when it's on edge it throws error somehow

Is there a workaround for this?
