Error: Adapter/build output error

SvelteKit needs the Cloudflare adapter for SSR on Cloudflare Pages. Static-only sites need adapter-static and matching output settings.

Step-by-step fix

Install @sveltejs/adapter-cloudflare for SSR Pages deployments.
Configure svelte.config.js with the adapter.
Set build command to npm run build.
Confirm Cloudflare output directory matches .svelte-kit/cloudflare or documented output.

import adapter from "@sveltejs/adapter-cloudflare";
export default { kit: { adapter: adapter() } };
