LuizArmesto opened a new issue, #30932:
URL: https://github.com/apache/airflow/issues/30932
### Apache Airflow version
main (development)
### What happened
When creating a DAG with Task Groups and a Mapped Operator, if the Task
Group is passed as an argument to Mapped Operator's `partial` method it is
ignored and the operator is not added to the group.
### What you think should happen instead
The Mapped Operator should be added to the Task Group passed as an argument.
### How to reproduce
Create a DAG with a source code like the following one
```python
from airflow import DAG
from airflow.operators.bash import BashOperator
from airflow.operators.empty import EmptyOperator
from airflow.utils import timezone
from airflow.utils.task_group import TaskGroup
with DAG("dag", start_date=timezone.datetime(2016, 1, 1)) as dag:
start = EmptyOperator(task_id="start")
finish = EmptyOperator(task_id="finish")
group = TaskGroup("test-group")
commands = ["echo a", "echo b", "echo c"]
mapped = BashOperator.partial(task_id="task_2",
task_group=group).expand(bash_command=commands)
start >> group >> finish
# assert mapped.task_group == group
```
