Issue happens with Cloudflare & Node.. So no adapter specific issue.

Hi @hkbertoson, thanks for reporting! I see you're using the Cloudflare adapter. Did you try the following?

1. Add the nodejs_als flag to your wrangler config. This allows a Node-specific API that actions relies on

# wrangler.toml
compatibility_flags = [ "nodejs_als" ]

2. Mark this Node API as external in your vite config:

import {defineConfig} from "astro/config";
import cloudflare from '@astrojs/cloudflare';

export default defineConfig({
  adapter: cloudflare({}),
  output: 'server',
  vite: {
    ssr: {
      external: ['node:async_hooks'],
    },
  },
})

I was also unable to reproduce this bug with the node adapter as @alexanderniebuhr noted above. If you can share a minimal reproduction with the node adapter that displays this issue, please share!

@bholmesdev I just took that assumption based on screenshots from here https://discord.com/channels/830184174198718474/1255555330646216785

That thread shows that the Cloudflare specific issue can be fixed with the solution you posted but that then the same error as node appears. I think it might be an issue on how it is used in this specific case.
