NEXT.js 13 Unhandled Runtime Error "Error: failed to load data" Explain with coding Example

Error: failed to load data

This error message indicates that there was an issue loading data in a Next.js application. This can happen for a variety of reasons, such as an issue with the API endpoint being called, an issue with the data being passed to the API, or an issue with the way the data is being handled in the application.

• To troubleshoot this issue, you can try the following steps:
• Check the API endpoint being called to ensure that it is returning the expected data.
• Check the data being passed to the API to ensure that it is in the correct format and that all required fields are present.
• Check the code that is handling the data to ensure that it is properly handling any errors or exceptions that may occur.
• Check the browser developer console for any errors or warnings that may provide more information about the issue.
• Check the server logs for any errors or warnings that may provide more information about the issue.

If you are unable to resolve the issue, it may be helpful to reach out to the developer or team responsible for the API or the application to see if they can assist you in resolving the issue.

Here is an example of a Next.js component that fetches data from an API endpoint:

import React, { useState, useEffect } from 'react';

import axios from 'axios';

const ExamplePage = () => {

  const [data, setData] = useState([]);

  const [error, setError] = useState(null);

  const [loading, setLoading] = useState(true);

  useEffect(() => {

    axios

      .get('https://api.example.com/data')

      .then((res) => {

        setData(res.data);

        setLoading(false);

      })

      .catch((err) => {

        setError(err);

        setLoading(false);

      });

  }, []);

  if (loading) {

    return <p>Loading...</p>;

  }

  if (error) {

    return <p>Error: {error.message}</p>;

  }

  return (

    <div>

      <h1>Data from API</h1>

      <ul>

        {data.map((item) => (

          <li key={item.id}>{item.name}</li>

        ))}

      </ul>

    </div>

  );

};

export default ExamplePage;

In this example, the component uses the useEffect hook to fetch data from the API when the component is rendered. The data, error, and loading states are managed using the useState hook. The component displays a "Loading..." message while the data is being fetched, and an error message if there is an issue with the API call. If the data is successfully fetched, it is displayed in a list.

You can check the example code and try to find the issue in your code by comparing and looking for any missing or different parts that can cause the error.
