### Apache Airflow version 2.1.2 ### Operating System Official docker image ### Versions of Apache Airflow Providers _No response_ ### Deployment Official Apache Airflow Helm Chart ### Deployment details Originally had airflow 2.0.2 installed via 3rd party helm chart (running external postgres db). I uninstalled it and installed airflow 2.1.2 using the official chart. Pods are alll started up except the schedular pod is crashing with "ValueError: unsupported pickle protocol: 5" ### What happened I get a "ValueError: unsupported pickle protocol: 5". I went into the database and did some cleanup but still getting error. Not sure if there are other tables/colums that also need to be cleaned up. Cleanup Done: UPDATE public.dag_run SET conf= NULL; DELETE FROM public.dag_pickle; Logs: File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 100, in instances cursor.close() File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/util/langhelpers.py", line 70, in __exit__ with_traceback=exc_tb, File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/util/compat.py", line 182, in raise_ raise exception File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 80, in instances rows = [proc(row) for row in fetch] File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 80, in <listcomp> rows = [proc(row) for row in fetch] File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 588, in _instance populators, File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 725, in _populate_full dict_[key] = getter(row) File "/home/airflow/.local/lib/python3.6/site-packages/sqlalchemy/sql/sqltypes.py", line 1723, in process return loads(value) File "/home/airflow/.local/lib/python3.6/site-packages/dill/_dill.py", line 275, in loads return load(file, ignore, **kwds) File "/home/airflow/.local/lib/python3.6/site-packages/dill/_dill.py", line 270, in load return Unpickler(file, ignore=ignore, **kwds).load() File "/home/airflow/.local/lib/python3.6/site-packages/dill/_dill.py", line 472, in load obj = StockUnpickler.load(self) ValueError: unsupported pickle protocol: 5 ### What you expected to happen _No response_ ### How to reproduce _No response_ ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
