Module not Found after commenting function in Next.js

Question

Could someone explain what is going. I have been trying to follow this tutorial https://nextjs.org/learn/basics/data-fetching/implement-getstaticprops I'm currently having issues with getStaticProps to work aso I started poking around and when i comment out getSortedPostsData(); or make it a string the getSortedPostsData module should be unused and I would have thought produce no errors however I get an error of cannot import fs from 'fs' which exists as an import within getSortedPostsData, why does this error occur?

import Head from 'next/head';
import styles from '../styles/Home.module.css';
import Link from 'next/link';
import { getSortedPostsData } from '../lib/posts';
import Layout from '../components/layout'
import utilStyles from '../styles/utils.module.css';
export async function getStaticProps() {
  console.log("get static props runs")
  const allPostsData = 'getSortedPostsData();'
  return {
    props: {
      allPostsData,
    },
  };
}


export default function Home({ allPostsData }) {
  return (
    <Layout home>

          {console.log(`info: ${allPostsData}`)}

}

I was expecting no error to occur when this is commented out and the module is not used.

You have a tagged template literal outside the commented code, so it makes the console.log function call with argument of `allPostsData` which results in your `getStaticProps` function getting called. — Anand Sowmithiran, Apr 15 '23 at 05:19
