Generated template.yml references incorrect CodeUri #1043

Open corey-cole opened 7 months ago

corey-cole commented 7 months ago

The initial template.yml generated at the root of the project has CodeUri: build/. Executing sam build results in a no-op obscured by a stack trace:

Skipping copy operation since source <my working directory>/alb-perimeter-hook/build does not exist

Error: [Errno 2] No such file or directory: '<my working directory>/alb-perimeter-hook/.aws-sam/build/TypeFunction'

Updating the generated template to CodeUri: src/ results in a working build result with no stack trace. The documentation doesn't explain how a build directory is/might be created, and none of the steps executed in the initial README result in a build directory.
