AWS Serverless Microservices with Patterns and Best Practices - Catch and Process Async EventBridge Invocation and Sync

The video tutorial explains how to handle asynchronous and synchronous invocations in AWS Lambda functions. It covers the understanding of event sources, such as Amazon EventBridge and API Gateway, and how to develop microservices to process these events. The tutorial includes writing pseudo code to differentiate between asynchronous and synchronous invocations, and emphasizes the importance of returning a synchronous response to avoid errors. The video concludes with a plan to implement the discussed methods in future videos.

Describe the process of handling incoming events in the Lambda function.

What should be returned in a synchronous API Gateway invocation?

What happens if a synchronous response object is not returned?
