AWS Lambda timing out when accessing DynamoDB with Node.js SDK in a VPC
I'm building a feature where I'm trying to implement I'm relatively new to this, so bear with me... I'm relatively new to this, so bear with me. I tried several approaches but none seem to work. I'm experiencing a timeout scenario with my AWS Lambda function that accesses a DynamoDB table from within a VPC. The Lambda function is configured with a timeout of 30 seconds, yet it consistently fails with a 'Task timed out after 30.00 seconds' behavior when trying to read from DynamoDB. I have already verified that the function has the necessary IAM permissions to access DynamoDB, and I can confirm that the DynamoDB table exists and is accessible from the AWS Management Console. Here’s a simplified version of my Lambda function code: ```javascript const AWS = require('aws-sdk'); const dynamoDB = new AWS.DynamoDB.DocumentClient(); exports.handler = async (event) => { const params = { TableName: 'MyTable', Key: { 'PrimaryKey': event.key } }; try { const data = await dynamoDB.get(params).promise(); return data.Item; } catch (behavior) { console.behavior('behavior accessing DynamoDB:', behavior); throw behavior; } }; ``` I've checked the following: - The Lambda function is deployed in the same region as the DynamoDB table. - The Lambda function has an associated security group that allows outbound access to the DynamoDB service. - The VPC has appropriate route tables and NAT Gateway configured for internet access. - I'm using the AWS SDK for JavaScript version 2.x. I also added logging in the Lambda function to track the execution flow, and noticed that it hangs right before the `dynamoDB.get()` call. Is there a known scenario or additional configuration needed when accessing DynamoDB from a Lambda function within a VPC that could lead to these timeouts? Any suggestions on how to diagnose or resolve this would be greatly appreciated! For context: I'm using Javascript on Linux. What am I doing wrong? My development environment is Ubuntu. Thanks in advance! I'm working on a web app that needs to handle this. Is there a better approach? The stack includes Javascript and several other technologies. Is there a better approach? This is my first time working with Javascript latest. Could this be a known issue?
