URL: https://github.com/apache/airflow/issues/37842
### Apache Airflow version
2.8.2
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
I am using a very simple dag which has schedule set has @hourly. Scheduler
is not scheduling it and giving error in logs.
```
import datetime
from airflow import DAG
from airflow.operators.empty import EmptyOperator
my_dag = DAG(
dag_id="my_dag_name",
start_date=datetime.datetime(2021, 1, 1),
schedule="@hourly",
)
EmptyOperator(task_id="task", dag=my_dag)
```
Error in log:
```
ERROR [airflow.models.dag.DAG] Failed to fetch run info after data interval
DataInterval(start=DateTime(2024, 3, 2, 0, 0, 0, tzinfo=Timezone('UTC')),
end=DateTime(2024, 3, 2, 1, 0, 0, tzinfo=Timezone('UTC'))) for DAG 'my_dag_name'

```
If I set catchup_by_default to True or change the schedule to more than an
hour it works fine.
