Hello @bclark
Thank you for reporting this. I think there has been a problem with the Airflow setup. If you run into the same issue again, can you please try restarting Airflow to see if it helps?
I ran into the same problem where both DAGs fail at ‘docker_dbt_command’, and still failed after I followed the lab instructions for resetting Airflow. Received 100/100 grading, but still disappointing to not be able to see this fully end to end before course completion.
