Navbar item and links disappear using adapter static

[spedone]

When i turn adapter to static in svelte.config.js the navbar items and links disappear.

svelte.config.js

import adapter from '@sveltejs/adapter-auto';
import { vitePreprocess} from '@sveltejs/kit/vite';
// import adapter from '@sveltejs/adapter-static';

/** @type {import('@sveltejs/kit').Config} */
const config = {
    // Consult https://kit.svelte.dev/docs/integrations#preprocessors
    // for more information about preprocessors
    preprocess: vitePreprocess(),

    kit: {
        // adapter-auto only supports some environments, see https://kit.svelte.dev/docs/adapter-auto for a list.
        // If your environment is not supported or you settled on a specific environment, switch out the adapter.
        // See https://kit.svelte.dev/docs/adapters for more information about adapters.
        adapter: adapter({
            // default options are shown. On some platforms
            // these options are set automatically — see below
            pages: 'build',
            assets: 'build',
            fallback: null,
            precompress: false,
            strict: true
          })

    },

};

export default config;

+layout.svelte

<script lang="ts">
  import {
    Collapse,
    Navbar,
    NavbarToggler,
    NavbarBrand,
    Nav,
    NavItem,
    NavLink,
    Image
  } from 'sveltestrap';

  let isOpen = false;

  function handleUpdate(event) {
    isOpen = event.detail.isOpen;
  }
</script>

<Navbar color="light" light expand="md">
