Encountering a Next.js prerendering issue when using getStaticPaths

Question

Encountering a Next.js prerendering issue when using getStaticPaths

I am currently developing a Next.js application. Here is the structure of my files:

cpanearme
 -components
   -listitem.js
 -pages
    -home
       -index.js
     -firm
        -[id].js

Below is the code for a list item that redirects to the dynamic route:

<a className='lead'
      onClick={() => {
        router.push({
          pathname: `/firm/${firm.id}`,
          query: { data: firm.id},
        })
      }}
>View Their Profile and Reviews</a>

The following is the complete dynamic page setup:

import { withRouter } from 'next/router'
import Image from 'next/image'
import Link from 'next/link'
import StickyNavbar from '../../components/StickyNavbar'
import ReviewItem from "../../components/ReviewItem"
import Footer from '../../components/Footer'
import path from "path"
import fs from "fs"

<!-- Rest of the JavaScript code -->

During the building phase, I encountered an error after implementing getStaticPaths. The specific issue is perplexing and does not yield relevant results when searched online.

Error: Export encountered errors on following paths:
        /firm/[id]
        /taxfaqs/[id]

Although everything passes successfully with get static props, I am unsure how to address the error related to [id]. Could it possibly be [...id] instead?

There appears to be some misunderstanding regarding the functionality of getStaticPaths and getStaticProps.

getStaticPaths is used in dynamic routes (such as /firm/[id]) to specify the list of paths that need to be pre-rendered to HTML during build time. This means you must return an array of potential paths for that particular route.

// Generates `firm/firm1` and `firm/firm2` paths during build time
export async function getStaticPaths() {
    return {
        paths: [
            { params: { id: 'firm1' } },
            { params: { id: 'firm2' } }
        ],
        fallback: true
    };
}

getStaticProps will then generate the props for each page based on the paths provided by getStaticPaths during build time.

// Generates props for a given path during build time
export async function getStaticProps({ params }) {
    // Implement your own logic to fetch data for the specified path and pass it to `firm`
    // If the route is like `/firm/firm1`, then params.id will be `firm1`
    return {
        props: {
            firm
        }
    };
}

Finally, in your page component, you can access the data passed through the props.

const Profile = ({ firm }) => {
    // The variable `firm` will hold the data for the specified path
}
