Start with the Petstore Spring Boot 2 deployment and the Lambda entry point named com.madman.lambda.StreamLambdaHandler. Inspect the Lambda configuration and deployed package to determine why that class is unavailable, then invoke the GET operation through the ALB or API trigger and confirm the ClassNotFoundException is gone.
