Describe the Bug

1. Create a new Cloudflare Workers project with npm create cloudflare@latest. Choose Framework Starter, then React or Vue. Accept default values for other options.
2. Start the dev server with proxy environment variables set. The dev server should work but it does not.

In the following example, an HTTP proxy server on port 11451 has been properly set up.

$ http_proxy=http://127.0.0.1:11451 npm run dev

> weathered-truth-0d9c@0.0.0 dev
> vite

Proxy environment variables detected. We'll use your proxy for fetch requests.
error when starting dev server:
