In the debugger I can see that before starting the scheduler the test task is added:

ScheduleJob(name='Snitch-TaskScheduler', base_task_id='', base_function=<function main.<locals>.scheduler_function.<locals>.<lambda> at 0x7f05e1ab3600>, queue='services', target_project='DevOps', single_instance=False, task_parameters=None, task_overrides=None, clone_task=True, _executed_instances=None, execution_limit_hours=None, recurring=True, starting_time=datetime.datetime(2024, 1, 17, 10, 50, 28, 738971), minute=10, hour=None, day=None, weekdays=None, month=None, year=None, _next_run=None, _execution_timeout=None, _last_executed=None, _schedule_counter=0)
