vercel-builder: Vercel deployments broken if @nuxt/content module is included (spa/static and SSR configs)

TL;DR - create a bare bones app using yarn create nuxt-app and include the @nuxt/content module. Deploy it to Vercel and the page errors out. This applies to every type of configuration, whether the target is static/server and whether SSR is on/off.

Static bug repo: https://github.com/nakedgun/nuxt-content-ssr-bug/tree/static SSR bug repo: https://github.com/nakedgun/nuxt-content-ssr-bug/

Both repos are basic apps created using yarn create nuxt-app. For reference:

1. yarn create nuxt-app
2. Include the nuxt content module when prompted
3. yarn add @nuxtjs/vercel-builder
4. nuxt.config.js

  ssr: false,
  target: 'static',

Deploy to Vercel / view page. Result: white page and error in console:

Different example with target = server | SSR = true and including serverFiles within vercel.json

nuxt.config.js

It’s worth noting that you don’t need any definition of the nuxt content module within nuxt.config.js or a vercel.json config to cause the problem. Simply having @nuxt/content in your package.json seems to break the builds. Everything works fine locally or when run via node/nginx.
