SvelteKit: "No overload matches this call" error invite.config.js when working with vitest

I just created an app with pnpx sv create sveltekit-test2

and checked vitest

and now when I run pnpm check I get this error:

Loading svelte-check in workspace: /home/sas/devel/apps/dgiit/proyectos/tmp/sveltekit-testGetting Svelte diagnostics.../home/sas/devel/apps/dgiit/proyectos/tmp/sveltekit-test/vite.config.ts:5:12Error: No overload matches this call.  The last overload gave the following error.

this is my vite.config.js

import { defineConfig } from "vitest/config";import { sveltekit } from '@sveltejs/kit/vite';export default defineConfig({    plugins: [sveltekit()],    test: {        include: ['src/**/*.{test,spec}.{js,ts}']    }});

and here's the same error on vscode

the defineConfig from the vite package works ok, btw
