slice bounds out of range when attempting to list consumers in a jetstream cluster

[TomHellier]

Observed behavior

I'm attempting to list the consumers in a jetstream cluster using exec via:

• the kubernetes dashboard.
• argocd terminal interface

This works if I use kubectl, but I don't readily have access to that in all of the environments I deploy to.

~ # nats consumer ls
panic: runtime error: slice bounds out of range [:-2]

It also looks like github.com/AlecAivazis/survey is out of life, so probably worth transitioning to an alternative

[ripienaar]

Yeah, its a bit sad - and the alternatives are not great from a dependencies perspective
