kmehkeri opened a new issue, #37091: URL: https://github.com/apache/airflow/issues/37091
### Apache Airflow version 2.8.1 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? When a task that uses dynamic task mapping has `trigger_rule='none_failed'` and depends on a task that was skipped, it fails with `upstream_failed` status.  ### What you think should happen instead? The dynamic task should be skipped as well (this happens with `trigger_rule='all_success'`. ### How to reproduce ``` import random from airflow.decorators import dag, task import datetime @dag( start_date=datetime.datetime(2021, 1, 1), schedule=None, ) def branch_with_mapping(): @task def random_fun(): import random return random.randrange(-10, 10) > 0 @task.branch def branching(x): if x is True: return "true_branch" else: return "false_branch" @task def true_branch(): print("True") return [1, 2, 3] @task def false_branch(): print("False") @task(trigger_rule='none_failed') def echo(i): print(i) t = true_branch() branching(random_fun()) >> [t, false_branch()] echo.expand(i=t) branch_with_mapping() ``` ### Operating System Using official Airflow Docker image in standalone mode ### Versions of Apache Airflow Providers _No response_ ### Deployment Other Docker-based deployment ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
