Please provide information as requested by the issue template, otherwise there is no way to identify the issue.

[amit151993]

As of now, there are no DAGs scheduled in Airflow, I removed all of the DAGs and restarted the Airflow Instance, still seeing the same issue.

@amit151993 @uranusjr is asking you to follow the issue template here. You omitted 'how to reproduce' in the issue template. Can you answer that? How can we reproduce your issue

[amit151993]

@ephraimbuddy I have included a temple for how to reproduce errors. Let me know, if it will require more information.

airflow 2.2.0 version

[potiuk]

Upgrade to latest.

[potiuk]

Converting to discussion until @amit151993 rechecks this in latest version of airflow. I believe the problem was caused by conflict of depdendencies. @amit151993 - make sure when you upgrade to follow https://airflow.apache.org/docs/apache-airflow/stable/installation/installing-from-pypi.html and use constraints to install airlfow (this is the only official/supported version to install airflow);
