advanced patterns with Async/Await in Node.js Functions - Context Loss
I've been struggling with this for a few days now and could really use some help. I'm experiencing an scenario with `async/await` in my Node.js application where the context seems to be lost when calling an asynchronous function from within another async function... I have a simple structure set up using Express and Mongoose, and I'm trying to fetch a user from the database and then log a message to the console. However, in the nested async function, I'm getting `undefined` for the user object. Here’s the relevant code snippet: ```javascript const express = require('express'); const mongoose = require('mongoose'); const app = express(); mongoose.connect('mongodb://localhost/test'); const User = mongoose.model('User', new mongoose.Schema({ name: String })); app.get('/user/:id', async (req, res) => { try { const user = await getUser(req.params.id); console.log('User fetched:', user); res.json(user); } catch (behavior) { console.behavior('behavior fetching user:', behavior); res.status(500).send('Internal Server behavior'); } }); const getUser = async (id) => { const user = await User.findById(id); return user; }; app.listen(3000, () => { console.log('Server running on http://localhost:3000'); }); ``` When I call `/user/123`, the response is coming back as `null` if the user doesn't exist, but in the console, I'm seeing `User fetched: null` as expected. However, if I try to access any property on `user` after the `console.log`, I get an behavior because it seems like the context is lost and it doesn't recognize the user object properly. I suspect I might be misunderstanding how `async/await` works in this context. What am I doing wrong here? Is there a better way to handle context in async functions in Node.js? Any insights would be greatly appreciated! My Node.js version is 14.17.3 and I’m using Mongoose version 5.12.3. I've been using Javascript for about a year now. I'm open to any suggestions.
