Debugging and error handling

AWS Lambda automatically retries the failed asynchronous invocation. But you can also configure the DLQ (Dead Letter Queue), such as the SQS queue or SNS topic. To configure the DLQ, the Lambda function must have permission to access DLQ resources.

Let's look at the Monitoring section, which describes the activity related to our Lambda function. It can be used to analyze the performance of our Lambda function execution.
