MatrixManAtYrService opened a new issue, #28106:
URL: https://github.com/apache/airflow/issues/28106
### Apache Airflow version
2.5.0
### What happened
Very simple dag:
```python3
from airflow import DAG
from airflow.operators.bash import BashOperator
from datetime import datetime, timedelta
with DAG(dag_id="hello_world", schedule=timedelta(days=30 * 365),
start_date=datetime(1970, 1, 1)) as dag:
(
BashOperator(task_id="hello", bash_command="echo hello")
>> BashOperator(task_id="world", bash_command="echo world")
)
```
Run it like `airflow dags test hello_world $(date +%Y-%m-%d)`
End of output:
```
