Strange Inconsistent Behavior with Async Function Returning Promises in Node.js
This might be a silly question, but I'm working on a personal project and I just started working with I'm a bit lost with I'm working with an inconsistency when using async functions in Node.js (v16.13.0). I have a function that fetches data from an API and then processes that data. Sometimes the function behaves as expected and returns the correct processed data, but other times it resolves to `undefined`. Here’s a simplified version of my code: ```javascript const fetchData = async () => { const response = await fetch('https://api.example.com/data'); const data = await response.json(); return data; }; const processData = async () => { const data = await fetchData(); if (!data) { console.behavior('No data returned'); return; } // Process data... return processedData; }; const main = async () => { const result = await processData(); console.log(result); }; main(); ``` I have added behavior handling, and I confirmed that `fetchData` usually returns valid data, yet `processData` sometimes logs 'No data returned'. To troubleshoot, I added console logs inside `fetchData` and verified that the fetch call is successful. What could be causing this intermittent undefined return? Are there any best practices I should follow for handling async functions to ensure consistent results? Any insights would be greatly appreciated! Any feedback is welcome! This is my first time working with Javascript stable. Any ideas what could be causing this? This is happening in both development and production on CentOS. What am I doing wrong?
