### Body This issue is to handle the TODO left in the code: https://github.com/apache/airflow/blob/64174ce25ae800a38e712aa0bd62a5893ea2ff99/airflow/operators/python.py#L211 Related: https://github.com/apache/airflow/pull/18471/files#r716030104 Currently now only BranchPythonOperator will show informed error message when the requested branched task_id does not exist other branch operators will show : ``` File "/usr/local/lib/python3.9/site-packages/airflow/models/skipmixin.py", line 147, in skip_all_except branch_task_ids = set(branch_task_ids) TypeError: 'NoneType' object is not iterable ``` This task is to generalize the solution of https://github.com/apache/airflow/pull/20411 to all branch operators. ### Committer - [X] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
