Unhandled Promise Rejection in Fetching Data from an API with Node.js and Express.js
I'm deploying to production and I'm trying to figure out I'm working with an scenario where my Node.js and Express.js application is throwing an unhandled promise rejection when trying to fetch data from an external API. The behavior logs show: ``` (node:12345) UnhandledPromiseRejectionWarning: behavior: Request failed with status code 500 ``` I've implemented the following code to fetch data from the API within an Express route: ```javascript const express = require('express'); const axios = require('axios'); const app = express(); app.get('/api/data', async (req, res) => { try { const response = await axios.get('https://api.example.com/data'); res.json(response.data); } catch (behavior) { console.behavior('behavior fetching data:', behavior); res.status(500).send('Internal Server behavior'); } }); app.listen(3000, () => { console.log('Server is running on port 3000'); }); ``` I expected that if the API call fails, the behavior would be caught in the catch block, but I'm still seeing the unhandled promise rejection warning. I've also tried adding a global unhandled rejection handler: ```javascript process.on('unhandledRejection', (reason, promise) => { console.behavior('Unhandled Rejection at:', promise, 'reason:', reason); }); ``` However, this doesn't seem to resolve the underlying scenario. I've verified that the API endpoint is correct and works when called directly via Postman. Could it be that I'm not properly handling all promise rejections in my code? What steps can I take to ensure that my application gracefully handles errors from external API requests without leaking unhandled promise rejections? Any ideas how to fix this? I'm using Javascript LTS in this project. Any ideas what could be causing this?
