I had cfn-lint as part of my Jenkins pipeline setup everytime a build has been triggered. It validates the CloudFormation templates on specified paths on the cloned repo. Everything was working fine but suddenly I started to get these error logs. Anyone know what is going on (Seems like a python related issue to me)?

```
