Can't create pull consumer from cli about natscli

[ripienaar]

The problem isn’t the pull consumer per se but the fact that work queue streams only allow one consumer to consume any subject.

So the error indicates you are trying to add a consumer that would clash with an existing one

@ripienaar, what existing one? There are no consumers to clash with.

Show “nats s info” please

Hmm, maybe the mirror counts as a consumer, which is weird, because when created via SDK, it works fine.

Could be yeah. Making a mirror of a WQ is probably not really a good idea. Try without the mirror?

[withinboredom]

Yep, that was it

[withinboredom]

Adding the mirror after the consumers works fine via cli.

[ripienaar]

What server version?

[withinboredom]

It's in the initial issue report.
