ClientError: An error occurred (ValidationException) when calling the DeleteMonitoringSchedule operation: Monitoring schedule in status Pending

Start with sagemaker_model_monitor/tensorflow/SageMaker-Model-Monitor-tensorflow.ipynb and reproduce the failure at In [34], where my_default_monitor.delete_monitoring_schedule() is called. Investigate the reported ValidationException for a schedule in Pending status; done means the notebook's CI run completes without this error and monitoring resources are cleaned up.
