Debugging AWS Lambda functions in production can be challenging due to insufficient logging. Temporarily enabling logging without redeploying is possible using a Lambda extension that supports Node.js. This extension, originating from tools like Lambda Live Debugger and ServerlessSpy, allows critical logging with minimal impact on the codebase. Detailed steps to build and use the extension, including setting environment variables and updating handlers, are provided. Important considerations include compatibility issues with other internal extensions.
