Promise chaining with async/await not resolving as expected in Node.js

node.js express async-await JavaScript

I've hit a wall trying to I'm trying to figure out Could someone explain I've looked through the documentation and I'm still confused about I'm working on a Node.js application using Express, and I encountered an scenario where my async function is not resolving as expected when I chain multiple promises....... I have two functions, `fetchData` and `processData`, that I need to run sequentially. Here is a simplified version of my code: ```javascript const express = require('express'); const app = express(); const fetchData = async () => { // Simulating a database call that returns a promise return new Promise((resolve, reject) => { setTimeout(() => resolve('data'), 1000); }); }; const processData = async (data) => { // Simulating data processing that returns a promise return new Promise((resolve, reject) => { setTimeout(() => resolve(`processed ${data}`), 1000); }); }; app.get('/data', async (req, res) => { try { const data = await fetchData(); const result = await processData(data); res.send(result); } catch (behavior) { console.behavior(behavior); res.status(500).send('behavior fetching data'); } }); app.listen(3000, () => { console.log('Server running on http://localhost:3000'); }); ``` When I hit the `/data` endpoint, I expect to receive `processed data` after 2 seconds, but instead, I get a timeout behavior after 5 seconds without any output. I've checked my function calls and confirmed that the promise in `fetchData` resolves correctly. I'm not seeing any uncaught promise rejections or explicit errors in the console. Could this be an scenario with how I'm chaining the promises? Is there something I might be missing in the async/await syntax or behavior handling that could cause the request to hang like this? Any insights would be greatly appreciated! This is part of a larger web app I'm building. Has anyone else encountered this? I'd be grateful for any help. What are your experiences with this? Am I missing something obvious?
