cloudflare-pages preset + streaming hangs

[Brendonovich]

I've been using vinxi + cloudflare pages via solid start for a while, but only recently have tried to enable streaming. With ssr: true and mode: 'stream' set, I get this warning from wrangler when running locally and none of my UI is served to the browser, just the entrypoint html.

▲ [WARNING] Failed to get worker definitions TypeError: fetch failed

You should be able to repdroduce it here.

1. pnpm install
2. pnpm build
3. pnpx wrangler pages dev dist
4. Go to http://localhost:8788 and notice that the full response is never sent, and the above warning should be logged after a short amount of time

I guess you wouldn't know when this showed up then. It may have never worked. I needed to change stuff to make cloudflare work in beta months ago for deployment but haven't touched it since. Then again I've never use wrangler locally to test stuff. It's complaining that fetch failed but the error is all internal to their stuff.

Yeah I think we might need more specific reproduction. I've deployed the latest hackers streaming and it seems ok: https://solid-hackernews.pages.dev/

We need to narrow this down more.

EDIT: Nvm I see there is a reproduction
