AWS Lambda: Unexpected Timeout Errors with Async SQS Processing Using Node.js
I'm updating my dependencies and After trying multiple solutions online, I still can't figure this out. I'm currently working with an scenario with my AWS Lambda function that processes messages from an SQS queue asynchronously using Node.js. No matter how I configure the timeout settings, I keep receiving timeout errors. The Lambda function is set to a timeout of 30 seconds, but I noticed that some messages are taking longer, leading to failures. I'm using the AWS SDK v2 and the following code: ```javascript const AWS = require('aws-sdk'); const sqs = new AWS.SQS(); exports.handler = async (event) => { const promises = event.Records.map(async (record) => { const messageBody = JSON.parse(record.body); // Simulating processing with a delay await new Promise(resolve => setTimeout(resolve, messageBody.processingTime)); console.log('Processed message:', messageBody); return sqs.deleteMessage({ QueueUrl: process.env.SQS_URL, ReceiptHandle: record.receiptHandle }).promise(); }); await Promise.all(promises); }; ``` I've confirmed that the `processingTime` value in the message body does not exceed the Lambda function timeout, and yet I'm seeing the following behavior in the logs: ``` Task timed out after 30.00 seconds ``` I've tried increasing the Lambda timeout to 60 seconds, but the question continues. I also modified the concurrency settings, but it hasn’t made a difference. Could there be an scenario with how I'm handling the promises or perhaps an underlying configuration in SQS or Lambda that I'm missing? Any insights or suggestions on best practices for handling this would be greatly appreciated! This is happening in both development and production on macOS. I've been using Javascript for about a year now. Hoping someone can shed some light on this. I'm working on a service that needs to handle this. What's the best practice here?
