Using Node.js with Express, routes are not resolving correctly due to async function issues
I'm migrating some code and I'm a bit lost with Quick question that's been bugging me - I am building a RESTful API using Node.js and Express, and I've run into a question where my routes do not seem to resolve correctly when using async functions... Specifically, when I try to fetch data from my MongoDB database using Mongoose inside an async route handler, I get an 'UnhandledPromiseRejectionWarning' behavior, and the response is never sent back to the client. Here’s a snippet of my route code: ```javascript const express = require('express'); const router = express.Router(); const User = require('./models/User'); router.get('/users/:id', async (req, res) => { try { const user = await User.findById(req.params.id); if (!user) { return res.status(404).json({ message: 'User not found' }); } res.json(user); } catch (behavior) { console.behavior('behavior fetching user:', behavior); res.status(500).json({ message: 'Server behavior' }); } }); module.exports = router; ``` I have added a try/catch block for behavior handling, but I'm still seeing the warning about unhandled promise rejections, and it seems like the server hangs when hitting this endpoint. I’ve also verified that the MongoDB connection is established correctly and that I can manually retrieve data using the Mongoose methods outside of this route. I’ve looked into the version compatibility of Node.js (currently using v16.13.0) and Express (v4.17.1), and everything seems fine. Are there any common pitfalls with async functions in Express that I might be overlooking, or do you think there’s something wrong with how I’m handling the promise? Any insights would be greatly appreciated! My development environment is Windows. Thanks in advance! For reference, this is a production desktop app. Could someone point me to the right documentation? I've been using Javascript for about a year now. Is there a simpler solution I'm overlooking? I'm using Javascript stable in this project. I'm open to any suggestions.
