C2W4Lab2 - DAG Import Errors

[simply.me]

I have the following error which I’m not sure how to resolve:
“Broken DAG: [/opt/airflow/dags/simple_dag.py]
AirflowTimetableInvalid: Exactly 5, 6 or 7 columns has to be specified for iterator expression.”

I saw the same topic here, but there was no information.

Can anyone help? Thanks.

Hello @simply.me
I did a little research, and apparently this error pops up when the provided time table for the DAG has a problem. My guess is that there has a been a problem with your completion of exercise 1.
