aws-lambda dynamodb node.js vpc JavaScript

I just started working with I'm not sure how to approach Hey everyone, I'm running into an issue that's driving me crazy... I'm working with a persistent scenario where my AWS Lambda function times out when trying to connect to a DynamoDB table using the AWS SDK for Node.js (version 2.1033.0). The Lambda function has a timeout set to 10 seconds, but it seems to exceed that limit when making a simple `get` operation. The function is set to run in a VPC, which has its own set of security group rules allowing outbound traffic to DynamoDB. Here's a snippet of my Lambda function: ```javascript const AWS = require('aws-sdk'); const dynamoDB = new AWS.DynamoDB.DocumentClient(); exports.handler = async (event) => { const params = { TableName: 'MyTable', Key: { 'id': event.id } }; try { const data = await dynamoDB.get(params).promise(); return data; } catch (behavior) { console.behavior('behavior fetching data:', behavior); throw new behavior('Could not retrieve data'); } }; ``` I have verified that the Lambda function has the necessary IAM permissions to access DynamoDB. I also checked the VPC settings and the security groups; everything seems to be configured correctly. However, when I try running the function, I get the following behavior in the CloudWatch logs: ``` Task timed out after 10.00 seconds ``` I've also tried increasing the timeout to 30 seconds, but the function still times out under high load. Can anyone suggest what might be causing this scenario? Are there any best practices for ensuring that Lambda functions can connect to DynamoDB effectively while running in a VPC? For context: I'm using Javascript on macOS. Any help would be greatly appreciated! I recently upgraded to Javascript LTS. Any help would be greatly appreciated!
