edieforvxvalue opened a new issue, #54514:
URL: https://github.com/apache/airflow/issues/54514
### Apache Airflow version
2.11.0
### If "Other Airflow 2 version" selected, which one?
2.10-composer
### What happened?
Airflow does not execute a downstream task that has status "all_done".
Status of upstream task:
```
Overall Status failed
112 Tasks Mapped
success: 94
failed: 10
skipped: 8
```
Status of Downstream task:
```
Overall Status no status
1 Task Mapped
no_status: 1
```
### What you think should happen instead?
The downstream task should execute, regardless of the status of upstream
tasks.
### How to reproduce
```python
import pendulum
import random
from airflow.decorators import dag, task
from airflow.exceptions import AirflowSkipException
@dag(
dag_id="dynamic_task_demo_clean",
start_date=pendulum.datetime(2025, 8, 14, tz="UTC"),
schedule=None,
catchup=False,
tags=["demo", "core", "dynamic-mapping"],
)
def dynamic_task_demo_clean():
@task
def generate_number_list():
return [random.randint(1, 1000) for _ in range(100)]
@task(task_id="square_num", trigger_rule="all_done")
def square_num(number: int):
possible_outcomes = ["succeed", "fail", "skip"]
chosen_outcome = random.choice(possible_outcomes)
if chosen_outcome == "succeed":
return number * number
elif chosen_outcome == "fail":
raise ValueError("This is a randomly triggered error.")
else:
raise AirflowSkipException("This task was randomly skipped.")
@task(task_id="add_seven", trigger_rule="all_done")
def add_seven(number: int):
if number is None:
return None
return number + 7
number_list = generate_number_list()
squared_numbers = square_num.expand(number=number_list)
add_seven.expand(number=squared_numbers)
dynamic_task_demo_clean()
```
