How can I speed up debugging for my Lambda functions?

For anyone using the AWS SAM CLI, you can invoke your Lambda functions locally, which is a big time-saver. I’ve found that running integration tests with real payloads helps catch issues early without long wait times.

Don’t forget about decent logging practices! Logging meaningful information can help you troubleshoot quicker without needing to re-deploy just to see a console log. And if you're using observability tools, pulling payloads from there can also streamline your debugging process.

One trick I've found useful is to structure your Lambda functions so that the main business logic is in a separate function. This way, you can run unit tests locally without having to deploy every time. It helps you debug faster and keeps your code clean!

You should definitely look into enabling the `--hotswap` option when running the CDK deploy command. It speeds up the deployment process significantly if no resources are blocking it. Also, tools like Lambda-live-debugger let you execute the function locally for quick testing.

Have you tried writing some solid unit tests for your Lambda function? Setting those up before deploying can really save time when it comes to debugging. Plus, using local simulation tools like LocalStack might help you run things without always going to the cloud.
