rodrigoassumpcao opened a new issue, #66101:
URL: https://github.com/apache/airflow/issues/66101
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.1
### What happened and how to reproduce it?
Cron presets such as `@quarterly` are not working in Airflow 3.2.1.
It appears that CronMixin does not check the cron_presets mapping before
instantiating croniter, causing preset expressions to fail validation.
### Version 3.2.1
```Python
@attrs.define
class CronMixin:
"""Mixin to provide interface to work with croniter."""
expression: str
timezone: str | Timezone | FixedTimezone
def validate(self) -> None:
try:
croniter(self.expression)
except (CroniterBadCronError, CroniterBadDateError) as e:
raise AirflowTimetableInvalid(str(e))
```
### Version 3.1.8
```Python
class CronMixin:
"""Mixin to provide interface to work with croniter."""
def __init__(self, cron: str, timezone: str | Timezone | FixedTimezone)
-> None:
self._expression = cron_presets.get(cron, cron)
if isinstance(timezone, str):
timezone = parse_timezone(timezone)
self._timezone = timezone
try:
# checking for more than 5 parameters in Cron and avoiding
evaluation for now,
# as Croniter has inconsistent evaluation with other libraries
if len(croniter(self._expression).expanded) > 5:
raise FormatException()
self.description =
self._describe_with_dom_dow_fix(self._expression)
except (CroniterBadCronError, FormatException,
MissingFieldException):
self.description = ""
```
