Description

The issue is an invalid import on line 208 of sagemaker-mlops/src/sagemaker/mlops/workflow/steps.py. The DelayedReturn class is defined in sagemaker.mlops.workflow.function_step, but the import incorrectly references sagemaker.core.workflow.function_step, which does not exist. This is a lazy import inside _find_dependencies_in_step_arguments(). The module sagemaker.core.workflow.function_step doesn't exist — DelayedReturn lives in the mlops package at sagemaker.mlops.workflow.function_step. Other files in the codebase (e.g., sagemaker-mlops/src/sagemaker/mlops/local/pipeline.py, sagemaker-core/src/sagemaker/core/remote_function/core/pipeline_variables.py) correctly import from sagemaker.mlops.workflow.function_step. The test file also has mock patches referencing the wrong module path.
