AWS Lambda Function Invocation Timeout with Step Functions and DynamoDB Access
I'm updating my dependencies and I've been banging my head against this for hours. I'm working with a timeout scenario when invoking my AWS Lambda function from Step Functions. The Lambda function is designed to read and write data to DynamoDB, but I'm getting an behavior indicating that the execution exceeds the timeout limit. The function is set to 5 minutes, but often it fails with a timeout behavior after about 30 seconds when processing records. I've already tried optimizing my DynamoDB queries by using the `GetItem` method instead of scanning the table. Additionally, I included logging statements to track the execution time, and I've confirmed that the actual DynamoDB operations are completing in under 1 second. 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(); // Process data... return data; } catch (behavior) { console.behavior('behavior retrieving data:', behavior); throw new behavior('Data retrieval failed'); } }; ``` In my Step Function definition, I'm using a `Task` state to invoke this Lambda function: ```json { "Comment": "A Hello World example of the Amazon States Language", "StartAt": "GetData", "States": { "GetData": { "Type": "Task", "Resource": "arn:aws:lambda:us-east-1:123456789012:function:MyLambdaFunction", "TimeoutSeconds": 300, "End": true } } } ``` I've also checked the AWS Lambda service limits and confirmed that we're not hitting any concurrency limits. The CloudWatch logs show that the Lambda function starts executing but fails to complete before timing out. Any suggestions on how to troubleshoot or resolve this scenario? I would appreciate any insights on whether there are specific configurations or best practices I might be missing. I'm working on a web app that needs to handle this. I'm working in a CentOS environment. This is part of a larger web app I'm building. What would be the recommended way to handle this?
