Proxy error when trying to redirect to external url

When using sveltekit and trying to do a simple redirect like

throw redirect(302, 'https://google.com')

throw redirect(302, 'https://google.com')

I'm getting the error:

[ERROR] Error: Could not proxy request: TypeError: fetch failed

Using the sveltekit template in npm create cloudflare The redirect works fine with npm run dev but doesn't with npm run pages:dev so likely a wrangler problem.

From looking at this again seems like the proxy is trying to fetch the redirected page. Get different errors for trying to redirect to different sites. I found _redirects but according to the docs for the cloudflare pages adapater (https://kit.svelte.dev/docs/adapter-cloudflare#notes) this doesn't effect server endpoints... Maybe there is a proxy config setting or something simple i'm missing?
