I can reproduce, a quick fix would be #452

Though the command is rather unintuitive as it basically requires a user id to be passed to work in all cases, but that is not required from the arguments.

I'll think a bit how we can refactor the command in general to further improve this.

I got the same problem, and I don't understand how to use your fix in #452 (I've updated the app)
