S3 ETL fails when "Build: enabled: False

[psgivens]

An example such as the following fails because the source output artifact doesn't match the deploy input artifact. I've provided the solution in this ticket.

- name: sample-s3-pipeline
  default_providers:
    source:
      provider: s3
      properties:
        bucket_name: packer-bucket-test
        object_key: input.zip
        account_id: 44444444444444
    build:
      enabled: False # if you wish to disable the build phase in a pipeline
    deploy:
      provider: s3
  targets:
    - target: 222222222222
      properties:
        bucket_name: test-adf-bucket-eu
        object_key: output.zip

S3 output artifact is "output-source".

    if self.category == 'Source':
        action_props["output_artifacts"] = [
            _codepipeline.CfnPipeline.OutputArtifactProperty(
                name="output-source"
            )
        ]

When Build is set to "enabled: false", CodeBuild is skipped and the S3 deploy's input artifact is "{0}-build".format(self.map_params['name']

    if self.category == 'Deploy':
        action_props["input_artifacts"] = [
            _codepipeline.CfnPipeline.InputArtifactProperty(
                name="{0}-build".format(self.map_params['name'])
            )
        ]

The generated CloudFormation for the pipeline fails with a complaint that there isn't an output format for "{0}-build".

Solution: Add a build the following block when building the Deploy action after the initial set block..

        if not self.map_params.get('default_providers', {}).get('build', {}).get('enabled', True):
            action_props["input_artifacts"] = [
                _codepipeline.CfnPipeline.InputArtifactProperty(
                    name="output-source"
                )
            ]
