Bug: SAM crash when using Fn::Transform in non Serverless resource

[having-fun-serverless]

Description:

I created and deployed a macro. When using this macro with a non Serverless construct, like DynamoDB, AWS SAM crashes. I'm aware of the issues with intrinsic functions as mentioned here - aws/serverless-application-model#2533 , but I'm using my function in a non Serverless resource.

Steps to reproduce:

I'm using the following template:

AWSTemplateFormatVersion: "2010-09-09"
Transform:
  - AWS::Serverless-2016-10-31
Description: >
  sam-app

  Sample SAM Template for sam-app

Globals:
  Function:
    Timeout: 3

Resources:
  HelloWorldFunction:
    Type: AWS::Serverless::Function
    Properties:
      FunctionName: "Test"
        
      InlineCode: |
        import json
        def handler(event, context):
          return {
            "statusCode": 200,
            "body": json.dumps({
                "message": "hello world",
            }),
          }
      Handler: index.handler
      Runtime: python3.11
      Architectures:
        - arm64
  
  MyNewTable:
    Type: AWS::DynamoDB::Table
    Properties:
      TableName: "MyNewTable"
      KeySchema:
        - AttributeName: key
          KeyType: HASH
      AttributeDefinitions:
        - AttributeName: key
          AttributeType: S
      Fn::Transform: TestMacro

Observed result:

When using aws cloudformation create-stack command to create a stack, it works, however when using sam deploy I'm getting

It looks like I was missing the name of the macro, although CW works without specifying the Name property, SAM requires something like
