`wrangler pages dev -- astro dev` fails to follow Astro redirects

Astro project with wrangler pages dev -- astro dev and default adapter fails to properly execute an Astro redirect return context.redirect("/login", 302) with [wrangler] Could not proxy request: TypeError: fetch failed. Deployed version works. Only dev fails. Astro runs on localhost:3000, and Wrangler on localhost:8788 Node 18.18.2

I assume, that CF is trying to proxy a 302 redirect, but instead of redirect Proxy fails on fetch.

return Response.redirect(url.toString(), 302)

return Response.redirect(url.toString(), 302)

I've been seeing the same thing with sveltekit. Makes the dev mode very difficult to use.
