vatsrahul1001 opened a new issue, #54627:
URL: https://github.com/apache/airflow/issues/54627
### Apache Airflow version
main (development)
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
Noticed scheduler is crashing when running mapped task
### What you think should happen instead?
Scheduler should not crash
### How to reproduce
1. Executed below mapped DAG
2. check scheduler logs
**DAG CODE**
```

@task
def get_delays():
return delays
@task
def get_wakes(delay, **context):
"Wake {delay} seconds after the task starts"

return (ti.start_date + timedelta(seconds=delay)).isoformat()
