edulauer opened a new issue, #41983:
URL: https://github.com/apache/airflow/issues/41983
### Apache Airflow version
2.10.0
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
When passing a list of task IDs to the **task_ids** argument in
**task_instance.xcom_pull**, instead of receiving a list of values returned by
each task, you might encounter a string with the value
'**LazySelectSequence**'."
In older versions of Airflow, such as 2.9.3, this issue did not occur.
### What you think should happen instead?
It should return a list of values pushed by each task mentioned in the
task_ids argument
### How to reproduce
with DAG as dag:
push_task = PythonOperator(
task_id='push_task',
python_callable=lambda: 'Hello, World!')
push_task_2 = PythonOperator(
task_id='push_task_2',
python_callable=lambda: 'Hello, World 2!')
def pull_function(**kwargs):
ti = kwargs['ti']
msg = ti.xcom_pull(task_ids=['push_task', 'push_task_2'])
print("received message: '%s'" % msg)
pull_task = PythonOperator(
task_id='pull_task',
python_callable=pull_function,
provide_context=True,
)
### Operating System
Debian GNU/Linux 12
### Versions of Apache Airflow Providers
_No response_
### Deployment
Docker-Compose
### Deployment details
FROM apache/airflow:2.10.0-python3.10
### Anything else?
In older versions of Airflow, such as 2.9.3, this issue did not occur.
