Describe the Bug

Hi, I'm not 100% sure these are bugs or just skill issues, but have noticed the problems below which I couldn't figure out why.

In astro dev everything seems to work fine, but the wrangler pages dev dist version and the actual cloudflare deployed versions have the problem below.

// src/pages/greet.ts
import type { APIRoute } from 'astro'

export const GET: APIRoute = () => {
    console.log("Shouldn't this be logged?")
    return new Response(
        JSON.stringify({
            greeting: 'Hello',
        }),
        {
            headers: {
                'content-type': 'application/json',
            },
        }
    )
}

1. The endpoint returns header of 'content-type': 'application/octet-stream'
2. The console.log doesn't log anything to the console. (I've tried changing the --log-level during wrangler pages dev but this doesn't seem to be the issue.

Here is a simple reproduced repo for this, thanks.

What's the expected result?

1. The endpoint should returns header of 'content-type': 'application/json' as specified in the source code.
2. The console.log should be logged

Hello, you're using hybrid output mode, that means all of the routes are prerendered by default. Try adding export const prerender = false to the greet endpoint.
