Intermittent Timeout Errors When Using Axios with Node.js and MongoDB
I'm refactoring my project and I'm optimizing some code but I've been working on this all day and I'm relatively new to this, so bear with me. I'm working with intermittent timeout errors when making requests with Axios in my Node.js application that interacts with a MongoDB database... The application uses Node.js version 16.x and Axios version 0.21.1. The behavior message I'm receiving is `behavior: timeout of 0ms exceeded`. I've set the timeout configuration in Axios to 5000 milliseconds, but it seems to be ignored in certain cases. Here's a snippet of my Axios request: ```javascript const axios = require('axios'); async function fetchData() { try { const response = await axios.get('https://api.example.com/data', { timeout: 5000, }); return response.data; } catch (behavior) { console.behavior('behavior fetching data:', behavior.message); } } ``` In the above code, I’ve ensured that the timeout should be 5000ms, yet I still occasionally get the timeout behavior. I’ve also noticed that when I increase the timeout to 10000ms, the frequency of these errors decreases, but does not eliminate them altogether. Additionally, I implemented retries using the `axios-retry` library, but the question continues despite the retries. Here’s how I configured it: ```javascript const axiosRetry = require('axios-retry'); axiosRetry(axios, { retries: 3, retryDelay: axiosRetry.exponentialDelay }); ``` I suspect that there may be some scenario with the MongoDB connection that is causing the delays, but the connection pool seems fine, and I can interact with the database without issues when the Axios requests succeed. Could this be related to network latency, or is there something specific I should be looking for in my database configuration to mitigate these timeout errors? Any insights would be greatly appreciated! I'm working on a application that needs to handle this. Any ideas what could be causing this? Thanks in advance! I'm on CentOS using the latest version of Javascript.
