Error building with @sveltejs/adapter-static after upgrading SvelteKit

[RiwEZ]

Describe the bug

I'm upgrading my SvelteKit version from "1.0.0-next.324" to "1.1.0" and I've already fixed everything to work on the dev server, but when I try to build with @sveltejs/adapter-static the error on the log came.

Reproduction

Try run npm run build on https://github.com/RiwEZ/TanatBlog on dev branch

Additional Information

As instructed in the issue template:

Reproductions must be short, self-contained and correct and must not contain files or code that aren't relevant to the issue — please do NOT just paste a link to your project.

So, I can't find a way to exactly reproduce the error I found. But I found something similar (maybe it's expected behavior, I don't know)

1. Create a folder [slug].json and +server.ts that will serve a GET that read some file like this

import type { RequestHandler } from './$types';
import { readFileSync } from 'fs';

const PATH = './src/data';
export const GET: RequestHandler = async ({ params }) => {
  const data = readFileSync(`${PATH}/${params.slug}.txt`, 'utf-8');
  return new Response(JSON.stringify({ data }));
};

2. Create a folder [slug] that will contain

<!-- +page.svelte -->
<script lang="ts"> 
    import type { PageData } from './$types';
    export let data: PageData;

    let t = data.text;
</script>
<div>{t}</div>

// +page.ts (if I use +page.server.ts, it'll also make the same error)
import type { PageLoad } from './$types';
import { base } from '$app/paths';

export const load: PageLoad = async ({ params, fetch }) => {
  const fetchURL = `${base}/${params.slug}.json`;
  const res = await fetch(fetchURL);
  const res_data = (await res.json());

  return { text: res_data.data };
};

3. Use @sveltejs/adapter-static and on +layout.server.ts add export const pretender = true to prerender everything.

If we try to use npm run build (vite build) it gives this error (npm run dev doesn't have any problems)

[Rich-Harris]

This is expected behaviour. The error tells you what happened — the route was not found while crawling your app. You need to link to any pages that you want to prerender, or put them in config.kit.prerender.entries
