404 deployed on Vercel Edge

[MickL]

I am using this module @nuxtjs/sitemap version 5.1.2 which works fine on localhost but unfortunately deployed to Vercel using NITRO_PRESET=vercel_edge is shows a 404. The 404 comes from Vercel itself, not from Nuxt.

/robots.txt generated by nuxt-simple-robots is available.

It seems that there are some presets with which sitemaps are not generated at all. in my case it is the github_pages preset.
I tried building locally with multiple presets and found the following

• works
  • node
  • netlify
  • static
• doesn't work
  • vercel (now that I know)
  • github_pages

I've pushed up a fix for github_pages as I was able to reproduce the issue. I have my personal site on Vercel and it seems to be working fine, Vercel Edge may have some issues though, didn't attempt to replicate.

I tried to debug this but I had no success, it looks like vercel is trying to serve a public file or something instead of hitting the server endpoint. There's no error logs though...

For the time being I'm forcing the prerender of the sitemap for vercel edge

Might need to do some rewrite magic...

vercel/vercel#6107

Should be an upstream Nitro bug though
