First of all, this project has helped me a lot in performing rolling upgrades of nodes on our Kubernetes cluster.
I have noticed that on Kubernetes Version 1.19 and above I get the following error message and the rolling upgrade process ends.

2021-04-22 15:35:16,787 ERROR 'NoneType' object is not iterable
I was able to fix this by upgrading the version of Kubernetes client to the latest version on pypi and get around this issue.
I am opening this issue to help others who might have been in a similar situation.
