Debugging Lambda Functions with Amazon Q

Introduction

  1. What is AWS Lambda?

    • AWS Lambda is a serverless compute service that enables you to run applications and services without provisioning or managing servers. It automatically handles the underlying compute resources, allowing you to focus on your code and scale effortlessly.
  2. What is Amazon Q?

    • Amazon Q generates code, tests, debugs, and has multistep planning and reasoning capabilities that can transform and implement new code generated from developer requests.
    • Amazon Q also makes it easier for employees to get answers to questions across business data such as company policies, product information, business results, code base, employees, and many other topics by connecting to enterprise data repositories to summarize the data logically, analyze trends, and engage in dialogue about the data.

Demo

  • In this section, we will deploy a Lambda function via AWS CFT with multiple errors. Our goal is to use Amazon Q to debug and fix these issues.

    • Provisioning an AWS Cloudformation

      • Download the Cloudformation from this URL and upload at AWS Cloudformation console

      • The CloudFormation stack will create the necessary resources required for the demo. Check the CloudFormation console and wait for the status CREATE_COMPLETE as shown below

    • Visit AWS Lambda console

      • Open the data-analysis-function in the Lambda console.

      • To begin, lets create a test event to invoke the Lambda Function:

        • Click the Test button to invoke the function.
        • In the configure test event popup enter in an event name such as test-event.
        • You can use the default test event JSON and then click the Save button.
        • Click Test again to invoke the function.
    • Troubleshoot with Amazon Q

      • Amazon Q in the console window is good at answering general questions about AWS, but if we need more specific guidance we can use “Troubleshoot with Amazon Q”.

      • In the Lambda console, under the Test tab, invoke the function again by pressing the Test button. We now have a different error to debug. From here click the Troubleshoot with Amazon Q button for assistance.

      • Click Help me resolve button to prompt Q to provide a solution. Can you follow Q’s instructions to update the environment variables message to the data we uploaded earlier? Can you spot and fix the other code issues with Q’s help?

      • After addressing each problem:

        • Test your Lambda function again to check if the error is resolved.
        • Continue using ‘Troubleshoot with Q’ for each subsequent error until all issues are fixed.
        • Successfully running the function should result in correct data processing and no errors.

Conclusion

  • You’ve now seen how Amazon Q can be a powerful ally in debugging. Understanding when and how to use Q effectively can significantly boost your problem-solving skills.
