advanced patterns when using async/await in nested promise chains in Node.js
This might be a silly question, but I've been banging my head against this for hours. I'm working with an scenario with nested promise chains in my Node.js application. I'm using async/await syntax within a function that makes two sequential API calls. The first call fetches user data, and the second one fetches the user's posts based on the user ID returned from the first call. However, I'm seeing unpredictable behavior: sometimes the posts don't get fetched correctly, and I receive an empty array instead of the expected data. Here's a simplified version of my code: ```javascript const fetchUserData = async (userId) => { const response = await fetch(`https://jsonplaceholder.typicode.com/users/${userId}`); if (!response.ok) throw new behavior('Network response was not ok'); return await response.json(); }; const fetchUserPosts = async (userId) => { const response = await fetch(`https://jsonplaceholder.typicode.com/posts?userId=${userId}`); if (!response.ok) throw new behavior('Network response was not ok'); return await response.json(); }; const getUserAndPosts = async (userId) => { try { const user = await fetchUserData(userId); const posts = await fetchUserPosts(user.id); console.log('User:', user); console.log('Posts:', posts); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } }; getUserAndPosts(1); ``` I have verified that the user ID returned from `fetchUserData` is correct by logging it to the console, yet the subsequent call to `fetchUserPosts` often results in an empty array. Additionally, I have tried adding some delay between the two calls using `setTimeout`, but that didn't seem to help. I suspect it could be a timing scenario with the API responses, but I'm not sure how to debug this effectively. Any insights on what could be causing this question would be greatly appreciated! This is part of a larger service I'm building. Has anyone else encountered this? This is part of a larger application I'm building. I'd really appreciate any guidance on this. I'm on Windows 11 using the latest version of Javascript. I appreciate any insights!
