How do I generate sourcemaps with Svelte and the adapter-static?

I have the following...

//vite.config.js
import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';

export default defineConfig({
    plugins: [sveltekit()],
    build: {
        sourcemap: true
    }
});
// svelte.config.js
import adapter from '@sveltejs/adapter-static';

/** @type {import('@sveltejs/kit').Config} */
const config = {
    kit: {
        // adapter-auto only supports some environments, see https://svelte.dev/docs/kit/adapter-auto for a list.
        // If your environment is not supported, or you settled on a specific environment, switch out the adapter.
        // See https://svelte.dev/docs/kit/adapters for more information about adapters.
        adapter: adapter({
            // default options are shown. On some platforms
            // these options are set automatically — see below
            pages: '../app/src/main/resources/static',
            assets: '../app/src/main/resources/static',
            fallback: null,
            precompress: false,
            strict: true
        })
    },
    compilerOptions: {
        sourcemap: true
    }
};

export default config;

However, when I run I do not see the sourcemaps being outputed when I run npm run build.

This question is not the same problem as you can see I have that property set. My guess is it is related to me using the resource-static.

How can I generate sourcemaps with the resource-static kit.
