issue with chaostoolkit-istio installation

[SapnaGirdhani1]

Hi Team,
Hi Team, facing a challenge with chaostoolkit-istio. I added this dependency in "requirement.txt" ( Python dependency file) and tried creating docker image, it fails.
it shows below exception. However when I read the exception it doesn't show anything related to istio, rather logzero. When I remove chaostoolkit-istio dependency then image gets created successfully. Please help.. Thanks!
