AWS Lambda Not Receiving Event Notifications from SQS Queue After VPC Configuration Changes
I've looked through the documentation and I'm still confused about This might be a silly question, but I'm sure I'm missing something obvious here, but I've configured an AWS Lambda function to process messages from an SQS queue, but after changing the Lambda's configuration to run inside a VPC, it stopped receiving events. The Lambda function was previously working correctly and is triggered by messages sent to the SQS queue. I'm using Node.js 14.x for the Lambda runtime. The function's IAM role has the necessary permissions for both SQS and VPC access. Here’s the behavior I’m working with when I check the CloudWatch logs: ``` Task timed out after 3.00 seconds ``` I’ve ensured that the Lambda has access to the necessary security groups and subnets. Here’s a snippet of how I set up the SQS integration in my Lambda function: ```javascript const AWS = require('aws-sdk'); const sqs = new AWS.SQS(); exports.handler = async (event) => { for (const record of event.Records) { console.log(`Processing message with ID: ${record.messageId}`); // Further processing... } }; ``` I've also checked the SQS queue settings to confirm that the Lambda function is set as a trigger. To troubleshoot, I tried sending messages directly to the queue and monitoring the Lambda function through the AWS console, but it remains inactive. I suspect it might be related to the VPC settings or security groups, but I’m not entirely sure where to look next. Any insights on how to resolve this scenario or what configurations I might be missing would be greatly appreciated. Is there a better approach? Has anyone else encountered this? I'm working in a Linux environment. Any feedback is welcome!
