AVMusorin opened a new issue, #31409:
URL: https://github.com/apache/airflow/issues/31409
### Apache Airflow version
2.6.1
### What happened
Sensor is fired with an exception ZeroDivisionError, if set up
`mode="reschedule"`, `exponential_backoff=True` and `poke_interval=1`
```
ERROR - Task failed with exception
Traceback (most recent call last):
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/sensors/base.py",
line 244, in execute
next_poke_interval = self._get_next_poke_interval(started_at,
run_duration, try_number)
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/sensors/base.py",
line 274, in _get_next_poke_interval
modded_hash = min_backoff + run_hash % min_backoff
ZeroDivisionError: integer division or modulo by zero
```
### What you think should happen instead
Throw an human-readable exception about corner values for `poke_interval` or
allow to set up this value less then 2 (if it's `>=` 2 - rescheduling works
fine.)
### How to reproduce
```
from airflow.sensors.base import BaseSensorOperator
from airflow import DAG
import datetime
class TestSensor(BaseSensorOperator):
def poke(self, context):
return False
with DAG("test_dag", start_date=datetime.datetime.today(), schedule=None):
sensor = TestSensor(task_id="sensor", mode="reschedule",
poke_interval=1, exponential_backoff=True, max_wait=5)
```
