Pickle protocol 5 is only implemented in Python 3.8+ and didn't exist when 3.6 was released, so it's pretty impossible it could be produced if the Python version never changed, as you suggested. Do you happen to have some clue how this got into your database? Maybe you used a 3.8 image to deploy Airflow 2.1.3 but accidentally switched to a 3.6 one for Airflow 2.2.0? -- This is an automated message from the Apache Git Service.
