Uncaught (in promise) Component not found: 7XekeXQ6f75GGMqJKbuH - Dynamic rendering with Next.js

The error message "Uncaught (in promise) Component not found: 7XekeXQ6f75GGMqJKbuH" in Next.js usually occurs when trying to render a dynamic page that doesn't exist or when the component being rendered is not found. In this answer, we will discuss dynamic rendering with Next.js and how to solve the "Component not found" error.

Dynamic rendering in Next.js is the process of generating pages based on dynamic data. It is achieved by creating pages with a [].js or [].ts file extension instead of a static .js or .ts file. For example, instead of creating a page called about.js, you would create a page called pages/about/[id].js.

To make the page dynamic, you can use the getServerSideProps or getStaticProps function to fetch data from an API or database and pass it as props to the page component. Here's an example of how to use getServerSideProps:

// pages/about/[id].js
import { useEffect, useState } from 'react';

export async function getServerSideProps(context) {
  const id = context.query.id;
  const res = await fetch(`https://api.example.com/data/${id}`);
  const data = await res.json();

  return {
    props: { data }, // will be passed to the page component as props
  };
}

function DynamicPage({ data }) {
  useEffect(() => {
    console.log(data);
  }, [data]);

  return <div>{JSON.stringify(data)}</div>;
}

export default DynamicPage;

In the example above, the getServerSideProps function fetches data based on the id query parameter and passes it as a prop to the DynamicPage component.

Now, let's discuss the "Component not found" error and how to solve it.

The error message "Component not found: 7XekeXQ6f75GGMqJKbuH" usually occurs when trying to render a dynamic page that doesn't exist or when the component being rendered is not found. To solve this error, you can check the following things:

1. Make sure the dynamic page file exists in the pages directory with the correct file name and extension. For example, if you're trying to access /about/123, make sure you have a file called pages/about/[id].js or pages/about/[id].ts.
2. Check that the component being rendered exists in the same file as the dynamic page. In the example above, the DynamicPage component is defined in the same file as the dynamic page.
3. Make sure the component name matches the exported name. In the example above, the component is named DynamicPage and is exported as the default export.
4. Check that the component is correctly imported. Make sure you're importing the component using the correct name and file path.
5. Check that the data is being fetched correctly. Use the console to check if the data is being fetched correctly and if it's being passed as a prop to the component.

By checking the above points, you should be able to solve the "Component not found" error in Next.js. If you're still having trouble, feel free to leave a comment below and I'll do my best to help you out.
