[Bug Report] Error while creating ProcessingStep

[usik]

Link to the notebook https://github.com/aws/amazon-sagemaker-examples/blob/main/end_to_end/nlp_mlops_company_sentiment/02_nlp_company_earnings_analysis_pipeline.ipynb

Describe the bug While creating a ProcessingStep such as below: create_dataset_step = ProcessingStep( name='HFSECFinBertCreateDataset', processor=create_dataset_processor, outputs=[sagemaker.processing.ProcessingOutput(output_name='report_data', source='/opt/ml/processing/output/10k10q', destination=f'{inference_input_data}/10k10q'), sagemaker.processing.ProcessingOutput(output_name='article_data', source='/opt/ml/processing/output/articles', destination=f'{inference_input_data}/articles')],

ProcessingOutput does not take pipeline parameter as a destination or source. It throws "TypeError: Pipeline variables do not support str operation."

To reproduce A clear, step-by-step set of instructions to reproduce the bug. SageMaker version: 2.88.3 Boto3 version: 1.22.10

1. Following the Notebook step by step until Step 1 where we create a processing step.
2. Also in Step 4, under the section "Create pipeline conditions to check if the Endpoint deployments were successful", there is also another processing step.

Logs If applicable, add logs to help explain your problem. You may also attach an .ipynb file to this issue if it includes relevant logs or output.

Changing

destination=f'{inference_input_data}/10k10q') destination=f'{inference_input_data}/articles')

to

destination=f'{inference_input_data.default_value}/10k10q') destination=f'{inference_input_data.default_value}/articles')

(and all subsequent instances of using this object for string interpolation) appears to fix the issue.
