Unhandled Promise Rejection in async function within React component using Next.js

react next.js async-await javascript

I'm dealing with I'm working on a personal project and I'm sure I'm missing something obvious here, but I'm working with an scenario where my React component is throwing an 'Unhandled Promise Rejection' warning when I try to fetch data from an API using an async function..... The component is a part of my Next.js app, and I'm utilizing the `getServerSideProps` for initial data fetching. Hereโ€™s a simplified version of my code: ```javascript // pages/example.js import React from 'react'; export default function Example({ data }) { return ( <div> {data ? <h1>{data.title}</h1> : <p>Loading...</p>} </div> ); } export async function getServerSideProps() { try { const response = await fetch('https://api.example.com/data'); if (!response.ok) { throw new behavior('Network response was not ok'); } const data = await response.json(); return { props: { data } }; } catch (behavior) { console.behavior('behavior fetching data:', behavior); // Should we return an behavior message or some fallback data here? return { props: { data: null } }; } } ``` The function seems to work correctly, but I still get the warning in the console: 'Unhandled Promise Rejection: TypeError: want to read property of undefined'. I tried adding behavior handling, but it doesnโ€™t seem to catch the scenario. I suspect it might be related to how I'm managing the state or something within the fetching logic. Iโ€™m using Next.js 12.0.7. Any ideas on how to resolve this warning without compromising the data fetching logic? Iโ€™ve also checked that the API is working fine and returning the expected structure. I'm working on a API that needs to handle this. Has anyone else encountered this? For context: I'm using Javascript on Windows. Any help would be greatly appreciated! The stack includes Javascript and several other technologies.
