Sitemap await not... well, waiting...

[petethered]

I'm trying to convert a SSG to SSR and found your extension which has been solving some of my sitemap issues. Thanks!

That being said, I'm running into issues trying to pull a list of ids to include in the sitemap for

During build, the await for fetch doesn't seem to be waiting.

[id].astro

import { fetchIds } from "../../data/items";
import sitemap from 'sitemap-ext:config';
sitemap(async ({ addToSitemap }) => {
  console.log("PreFetch");
  const ids = await fetchIds();
  console.log(ids);
  addToSitemap(
    ids?.data?.ids?.map((post) => ({
      id: post,
    }))
  );
});

items.ts

  try {
    console.log(`http://server/staticGenerator/items?allId=1`);
    const response = await fetch(`http://server/staticGenerator/items?allId=1`);
    console.log("Res: ", response);
    
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    
    const data = await response.json();
    return data;
  } catch (error) {
    console.error("Error", error);
    return {};
  }
};

Running build shows the "PreFetch", and the url in the console log, but nothing happens... the request isn't made.

Mind telling me what I'm missing?
