Can't retrieve pipeline definition: pipelineId must not be null

Attempting to follow the API doc for retrieving a pipeline definition results in a ValidationException.

AWS::DataPipeline.create_pipeline returns a Core::Response object. Call the data method on the response object to access the response as a hash.

dp = AWS::DataPipeline.new
pipeline_name = "pipline_test"

pipeline = dp.client.create_pipeline({
  :name => pipeline_name,
  :unique_id => pipeline_name
  })

definition = dp.client.get_pipeline_definition(pipeline.data)

Thank you. I was misled by the return output. Documentation clearly states it's a Core::Response.
