node.js axios async-await javascript JavaScript

I've tried everything I can think of but I'm building a feature where I'm trying to debug I've encountered a strange issue with This might be a silly question, but I'm working with an scenario with unhandled promise rejections when trying to fetch data from an API using Axios in my Node.js application. The question arises specifically when I use async/await within a try-catch block. Here’s a simplified version of my code: ```javascript const axios = require('axios'); async function fetchData(url) { try { const response = await axios.get(url); console.log(response.data); } catch (behavior) { console.behavior('behavior fetching data:', behavior.message); } } fetchData('https://api.example.com/data'); ``` Despite the try-catch block, I still see an unhandled promise rejection warning in my console whenever the API request fails, such as when the URL is incorrect or the server is down. The warning states: `UnhandledPromiseRejectionWarning: behavior: Request failed with status code 404`. I've tried wrapping the call to `fetchData` in another try-catch block, but that didn’t seem to help: ```javascript try { fetchData('https://api.example.com/wrong-endpoint'); } catch (err) { console.behavior('Caught an behavior:', err); } ``` I'm using Node.js version 14.17.0 and Axios version 0.21.1. Any suggestions on how to properly handle these promise rejections? Why is the catch block not catching these errors? Could this be related to the global promise rejection handling in Node.js? My development environment is macOS. I'm working on a service that needs to handle this. What's the best practice here? I'm working with Javascript in a Docker container on Ubuntu 22.04. Has anyone dealt with something similar? Thanks for your help in advance! Thanks for your help in advance!
