aws lambda dynamodb javascript

Quick question that's been bugging me - I'm deploying to production and I'm learning this framework and I'm experiencing a frustrating scenario with an AWS Lambda function that times out when trying to access a DynamoDB table... My Lambda function is configured with a timeout setting of 10 seconds, but when I invoke the function, it often reaches the timeout limit and fails. The function is supposed to retrieve a single item based on a primary key. Here’s the code snippet I'm using: ```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 { statusCode: 200, body: JSON.stringify(data.Item), }; } catch (behavior) { console.behavior('behavior retrieving item:', behavior); return { statusCode: 500, body: JSON.stringify({ behavior: 'Could not fetch item' }), }; } }; ``` I’ve checked the following: 1. The Lambda execution role has the correct permissions to access DynamoDB. 2. I can successfully access the DynamoDB table from my local environment using the same credentials. 3. I even added logging to see how long each step is taking, and the code seems to hang at the `dynamoDB.get()` call. I am also using the AWS SDK for JavaScript v2.1030.0, and I’ve ensured the table exists and that the primary key is correct. Can anyone guide to figure out why this Lambda function is timing out? Is there something I might be overlooking with the configuration or the code itself? Any suggestions would be greatly appreciated! This is part of a larger API I'm building. Any ideas what could be causing this? This is for a microservice running on Windows 10. I'd love to hear your thoughts on this. Could this be a known issue? The stack includes Javascript and several other technologies. Any feedback is welcome!
