We have installed Airflow 2.1.3 version in Linux server, worker is also available in the same server and while we are trying to run the job it says
Error: ValueError: unsupported pickle protocol: 5
airflow.exceptions.AirflowException: Celery command failed on host ******
Task level log:
*** Failed to fetch log file from worker. The request to ':///' is missing either
Currently using Python 3.6.8 version.
Is there any way to overcome this issue.
