Describe the Bug

After running remix dev with Wrangler v3.9.0, when I tried to reload the Remix app, the server was terminated with the error message: "Error [ERR_IPC_CHANNEL_CLOSED]: Channel closed." However, Wrangler v3.8.0 seems to work without any issues.

Steps to reproduce:

1. Setting up a new project (npm create cloudflare@latest my-remix-app -- --framework=remix)
2. move to remix dir (cd my-remix-app)
3. run remix (npm run dev)
4. edit files to live-reload

Please provide a link to a minimal reproduction

Can confirm same issue per this and remix-run/remix#7510 and downgrading from wrangler 3.9.0 to 3.8.0 resolved it for me

I am also getting ERR_IPC_CHANNEL_CLOSED on each change to my functions files when using vite, and not remix.

I caught that too in Remix, but it happens whenever the content of the functions directory is updated, no matter the tooling.

Seems that this is due to this code change. @mrbbot

I had the same issue and removing that line fixed it for me.
As a temporary workaround, I've created a patch using patch-package.
