Bun & Vite request failures

Bun will throw this whenever you access http://localhost:9926/ with Vite:
```
[http/1] [error]: TypeError: null is not an object (evaluating 'req.url')

Reproduce the failure by accessing http://localhost:9926/ with Bun and Vite, then start at dist/server/REST.js:71 and the related call around line 322 shown in the trace. Check how the request reaches Vite's node.js handler; done means the request no longer throws the null req.url error.
