malformed string exception in Jenkins

I am executing a python script on a jenkins slave.

verify-registry.py --env stage --repospec '^vipul-docker-*'

On the Jenkins console output it is giving me the "malformed string exception" for the repository. (the build is successful but output is not as expected)

However On the CLI it works perfectly.

[CONFIRM_ERROR]: vipul-docker-test-container: Confirm error

python versions are same on both cli and jenkins
