CLI (please complete the following information):

• OS: Ubuntu
• Version 20.04 Additional context I love this tool, you guys are awesome. I worked around this issue by using a version released closer to the OS release that supported the functionality I needed (v1.0.3)... I'm sure this may be expected behaviour with breaking changes in logic between major versions, just want to share it for completeness. Thank you so much for your incredible, generic tool
