You have the following options:
  - set the \`fallback\` option — see https://svelte.dev/docs/kit/single-page-apps#usage for more info.
  - add \`export const prerender = true\` to your root \`+layout.js/.ts\` or \`+layout.server.js/.ts\` file. This will try to prerender all pages.
  - add \`export const prerender = true\` to any \`+server.js/ts\` files that are not fetched by page \`load\` functions.
${config_option}
  - pass \`strict: false\` to \`adapter-static\` to ignore this error. Only do this if you are sure you don't need the routes in question in your final app, as they will be unavailable. See https://github.com/sveltejs/kit/tree/main/packages/adapter-static#strict for more info.

If this doesn't help, you may need to use a different adapter. @sveltejs/adapter-static can only be used for sites that don't need a server for dynamic rendering, and can run on just a static file server.
See https://svelte.dev/docs/kit/page-options#prerender for more details`
