🐛 BUG: Redirects not working with Astro (Could not proxy request: TypeError: fetch failed)

[smnschmnck]

Pages

What version(s) of the tool(s) are you using?

3.32.0 [Wrangler]

What version of Node are you using?

20.11.1

What operating system and version are you using?

Fedora Linux 39

Describe the Bug

Observed behavior

When using redirects to external pages in Astro like this: return context.redirect("https://example.com") I get this error: [wrangler] Could not proxy request: TypeError: fetch failed.

I bootstrapped my project with the npm create cloudflare@latest my-astro-app -- --framework=astro command.

The bug only happens when I start the dev server with the npm run pages:dev command. If I start via npm run dev everything works as expected but this way the Cloudflare bindings cannot be used so I need to use the pages command.

Expected behavior

The redirect should redirect to the desired page as expected.

Steps to reproduce

• Bootstrap an Astro project via the npm create cloudflare@latest my-astro-app -- --framework=astro command
• Create a redirect to an external page with this line return context.redirect("https://example.com") in an API route or create a redirect in an Astro page
• Run the setup via npm run pages:dev
• Visit the route with the redirect
• Observe the URL bar and check if the domain has changed

I have the issue that redirects do redirect but the url in the browser's url bar stays unchanged. This happens only when wrangler does proxy, not in production and not when accessing the underlying SvelteKit server directly.
