AWS::Serverless::Function CodeUri no longer supports Files

Description:

Previous to sam-cli 1.2 you could specify a ZIP file in the CodeUri parameter. Now receiving error that the path in the CodeUri must be a directory.

Lambda: Type: AWS::Serverless::Function Properties: Handler: test.LambdaRuntime Runtime: provided CodeUri: ./lambda.zip

Steps to reproduce:

Create a lambda compatible zip file and specify the zip file in the CodeUri: parameter

Observed result:

Receive error that sam cli expects the ./lambda.zip file to be a directory.

Error: CustomMakeBuilder:CopySource - [Errno 20] Not a directory:

Expected result:

I expect the ‘sam build’ command to completely successfully like v1.19.1 did.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: MacOS Big Sur 11.2.2
2. sam --version: 1.2
3. AWS region: us-east-1

@aahung You can see the whole project and directory structure at https://github.com/formkiq/formkiq-core/releases/download/v1.2.8/formkiq-core-1.2.8.zip.

My build process is completely independent of SAM build. I use SAM as a tool to deploy applications to AWS and not a build tool. This allows me to take a number of separate components and combine them into 1 application / cloudformation template.

I am gonna close this issue since the main problem is a duplicate of #2692. Thanks!
