   I managed to avoid the problem by unwraping the xcom like so:
   ```
   trigger_another_dag = TriggerDagRunOperator(
       task_id='trigger_another_dag',
       trigger_dag_id='another_dag',
       dag=dag,
       conf={
             'foo': "{{ ti.xcom_pull(task_ids='task1', key='return_value')['foo'] }}", 
             'bar': "{{ ti.xcom_pull(task_ids='task1', key='return_value')['bar'] }}", 
       }
   )
   ```
   As an alternative it works fine. Another solution would be to return multiple elements from the `PythonOperator`. IMO individually fetching them in `conf` is still inconvenient. 
   Please feel free to indicate what i do wrong in this in this configuration.
