Languages Available: Español (Latinoamérica) | 日本語 | 한국어 | Português (Brasil) | 中文（简体)

Your goal is to identify and remediate any configuration issues so that the API returns a “Hello from Lambda” response with a 200 status code.

Amazon API Gateway Lambda proxy integration is a simple, powerful, and nimble mechanism to build an API with the setup of a single API method. The Lambda proxy integration allows the client to call a single AWS Lambda function in the backend. The function accesses many resources and features of other AWS services.

Your goal is to identify and remediate any configuration issues so that the API returns a “Hello from Lambda” response with a 200 status code.

In this lab, you troubleshoot and fix an API Gateway with a Lambda proxy integration. When the API is invoked, you get an “Internal server error” response with a 500 status code.

Your goal is to identify and remediate any configuration issues so that the API returns a “Hello from Lambda” response with a 200 status code.
