I was unable to produce a repro outside of our proprietary repo unfortunately, definitely tried, open to ideas about what I might need to replicate.
Describe the Bug
We're seeing a consistent issue when we change our vite config and the cloudflare plugin tries to restart the workerd process. When this code runs at startup everything is fine, but when we update our vite config and this code runs again it throws an EBADF error that I can't quite wrap my head around.
I'm not 100% sure this is actually a workerd issue, but the error is definitely coming from the workerd library and I'm really hoping that someone might have a brilliant idea that helps explain why this is happening. If nothing else, it was surprising that nobody has filed such an issue yet.
