No manifest available.

new FetchState(request) was called outside of an Astro server, so no manifest is available.

What went wrong?

new FetchState(request) can only be used inside an Astro server — the built server output or the dev server — where Astro provides the manifest describing your site. This error means it was called somewhere else, for example in a plain Node script that imports astro/fetch.

If this error occurs inside an Astro-built server, please open an issue.
