Hooks with redirect break during build with adapter-node after @sveltejs/kit next.433

[fmaclen]

I'm not entirely sure if this is a bug or my implementation is mistaken.

Here's what my code looks like:

// src/hooks.ts

export const handle: Handle = async ({ event, resolve }) => {
	if (shouldRedirect) {
		return Response.redirect(`${event.url.origin}/some-route`, 307);
	} else {
		return await resolve(event);
	}
};

When I run npm run build using adapter-node@1.0.0-next.87 the last few lines of the logs look like this:

.svelte-kit/output/server/chunks/hooks.js                                     0.52 KiB
  307 / -> http://sveltekit-prerender/some-route
  307 /route-one -> http://sveltekit-prerender/some-route
  307 /route-two -> http://sveltekit-prerender/some-route
  307 /route-three -> http://sveltekit-prerender/some-route

Then, running npm run preview (when the redirect condition is matched) my browser is redirected to http://sveltekit-prerender/some-route which is obviously not a valid URL.

The code above was working fine up until @sveltejs/kit@1.0.0-next.432 so I'm guessing the behavior changed on #6179

Code works as expected when npm run dev.

After further investigation I was able to solve the issue by disabling prerender in svelte.config.js globally.

I'm not sure if there's a way to disable prerendering for specific conditions in hooks.ts but disabling it globally works in my case.

@tcc-sejohnson can you confirm if this is the expected behavior or should I open an issue?

There is already an open issue and I give temp workaround.
