TypeError: __init__() missing 2 required positional arguments in Airflow timetable

I am trying to implement a parameterized timetable following this https://airflow.apache.org/docs/apache-airflow/stable/howto/timetable.html#parameterized-timetables and I am getting the following error message in the logs: TypeError: __init__() missing 2 required positional arguments: 'hour' and 'minute'. This is the timetable code:

`class EveryFiscalPeriod(Timetable):    
    def __init__(self, hour: int, minute: int) -> None:
        self._hour = hour
        self._minute = minute

    def next_dagrun_info(
        self,
        *,
        last_automated_data_interval: Optional[DataInterval],
        restriction: TimeRestriction,
    ) -> Optional[DagRunInfo]:
        delta = timedelta(days=28)
        if last_automated_data_interval is not None:  # There was a previous run on the regular schedule.
            next_start = last_automated_data_interval.end
            next_end = last_automated_data_interval.end + delta
        else:  # This is the first ever run on the regular schedule.
            restriction_earliest = restriction.earliest
            next_start = restriction_earliest - delta
            if next_start is None:  # No start_date. Don't schedule.
                return None
            next_end = restriction_earliest

        return DagRunInfo(
            data_interval=DataInterval(start=next_start, end=next_end),
            run_after=DateTime.combine(next_end.date(), Time(self.hour), Time(self.minute)).replace(tzinfo=UTC),
    )`

In my DAG code I am passing the hour and minute into the class so I shouldn't be getting this error. The timetable itself without parameters works, but it breaks when I make it parameterized.

`with DAG(
    catchup=False,
    .........
    ),
    max_active_runs=1,
    schedule=EveryFiscalPeriod(hour=15, minute=30),
)......`

Any help will be much appreciated.

Looking at this file https://apache.googlesource.com/airflow/+/HEAD/airflow/timetables/base.py#168 per the stack trace the default deserialize method doesn't return hour and minute. Per the guide it looks like I need to override the method to return those params.
