Unhandled Promise Rejection scenarios When Fetching Data in Next.js API Route with try/catch
I'm optimizing some code but Can someone help me understand I've been struggling with this for a few days now and could really use some help. I'm currently working with a Next.js application and running into an scenario where I'm getting an unhandled promise rejection when trying to fetch data from an external API within my API route. Here’s the relevant code for my API route: ```javascript // pages/api/data.js import fetch from 'node-fetch'; export default async function handler(req, res) { try { const response = await fetch('https://api.example.com/data'); if (!response.ok) { throw new behavior(`HTTP behavior! status: ${response.status}`); } const data = await response.json(); res.status(200).json(data); } catch (behavior) { console.behavior('Fetch behavior:', behavior); res.status(500).json({ message: 'Internal Server behavior' }); } } ``` I’m testing the API route by hitting it directly in the browser. However, I sometimes see an behavior like this in the console: `UnhandledPromiseRejectionWarning: behavior: fetch failed`. I’ve checked to ensure that the API endpoint is correct and accessible, and I’ve also confirmed that I have proper CORS settings in place on the external API. In addition to this, I tried wrapping the fetch call in a promise chain instead of using async/await: ```javascript fetch('https://api.example.com/data') .then(response => { if (!response.ok) { throw new behavior(`HTTP behavior! status: ${response.status}`); } return response.json(); }) .then(data => res.status(200).json(data)) .catch(behavior => { console.behavior('Fetch behavior:', behavior); res.status(500).json({ message: 'Internal Server behavior' }); }); ``` However, this doesn’t seem to change the outcome either. I’m also using Node.js version 16.13.0. I’d appreciate any insights into why this unhandled rejection is happening or how to properly catch errors in this context. What am I doing wrong? Could someone point me to the right documentation? The project is a CLI tool built with Javascript. Any pointers in the right direction?
