I'm working through the Coursera course "Serverless Data Analysis with Google BigQuery and Cloud Dataflow" and Lab 2c (and the previous lab) both fail to complete with the cryptic message
(bc5242b016f8bade): Workflow failed. Causes: (bc5242b016f8b199): The Dataflow appears to be stuck. Please reach out to the Dataflow team at http://stackoverflow.com/questions/tagged/google-cloud-dataflow.
My Cloud Shell startup reads as follows. Note the SLF4J messages. The Job panel reports vCPU time and other statistics but the Step panels and Module dialog boxes show no information. I have tried removing the entire /training-data-analyst folder and recreating it and get the same problem.
