[GitHub] [airflow] gcerar opened a new issue, #24839: PythonVirtualenvOperator can't access task_instance variable

gcerar opened a new issue, #24839:
URL: https://github.com/apache/airflow/issues/24839

   ### Apache Airflow version
   
   2.3.2 (latest released)
   
   ### What happened
   
   Using the provided minimal example, `task_instance` (i.e., `ti`) is accessible when using `PythonOperator` but fails when using `PythonVirtualenvOperator`.
   
   ### What you think should happen instead
   
   I would expect `PythonOperator` and `PythonVirtualenvOperator` to behave in a similar way. Instead, none of the xcom examples example work with `PythonVirtualenvOperator`.
   
   ### How to reproduce
   
   Switch between `PythonOperator` and `PythonVirtualenvOperator`. Using `PythonVirtualenvOperator` dag will fail.
   
   ```python
   from airflow import DAG
   from airflow.operators.python import PythonVirtualenvOperator, PythonOperator
   from datetime import datetime, timedelta
   
   def _pusher(ti):
       ti.xcom_push(key='my-key', value='my-value')
   
   def _puller(ti):
       value = ti.xcom_pull(task_ids='pusher', key='my-key')
       assert value == 'my-value'
   
   with DAG('minimal-example', schedule_interval='@once', start_date=datetime(2021, 1, 1), catchup=False) as dag:
       #pusher = PythonVirtualenvOperator(
       pusher = PythonOperator(
           task_id='pusher',
           python_callable=_pusher,
           #requirements=[],
       )
   
       #puller = PythonVirtualenvOperator(
       puller = PythonOperator(
           task_id='puller',
           python_callable=_puller,
           #requirements=[],
       )
   
       pusher >> puller
   ```
   
   ### Operating System
   
   Ubuntu 20.04
   
   ### Versions of Apache Airflow Providers
   
   Apache airflow 2.3.2 in docker container
   
   ### Deployment
   
   Docker-Compose
   
   ### Deployment details
