> if you use {{timedelta=__anything__}}, and have {{catchup=False}}, it will cause a DOUBLE run of your DAG! The only workaround i found was to use a cron timer, i.e.,
> schedule_interval='@daily',
> Rather than
> schedule_interval=timedelta(days=1),
> It almost definitely exists in
> def create_dag_run(self, dag, session=None):
> in {{/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/airflow/jobs/scheduler_job.py }}
> around line {{643}}
