Pre-built workflow "wf-rmdm" failed to run - "Debugging in Data Modeling" course

Hi everyone, in the "Debugging in Data Modeling" course in Cognite Hub, one of the prerequisites is to load an already built Data Workflow "wf-rmdm" and run it to instantiate "RMDM" with instances. The course indicate that the workflow should be deployed and then run to be able to perform the next steps. I have loaded successfully the Data workflow, however, when trying to run it as suggested in the course, I get the following error message "Workflow could not be run". The course suggests the workflow should be successful. I do not know where to find more detailed logs about this error. The expected tables are loaded as well as all the Transformations. Any idea on how to overcome this situation ?
