Content View Filter rule not shown in hammer

Problem:
I have to automatically publish a new version of my content views based on some dates.
The logic is simple, but I have trouble with hammer.
Specifically, the

hammer content-view filter rule list --content-view-filter-id ##

is empty!

Of course, there are rules in that filter. My data are:

hammer content-view list --nondefault true
----------------|-----------------|-----------------|-----------|---------------------|------------------------------
CONTENT VIEW ID | NAME            | LABEL           | COMPOSITE | LAST PUBLISHED      | REPOSITORY IDS               
----------------|-----------------|-----------------|-----------|---------------------|------------------------------
9               | CentOS7 - Basic | CentOS7_-_Basic |           | 2018/12/12 10:13:49 | 4, 2, 1, 10, 3, 11, 6, 157, 5
----------------|-----------------|-----------------|-----------|---------------------|------------------------------

The CV’s filters are:

 hammer content-view filter list --content-view-id 9
----------|--------|---------|----------
FILTER ID | NAME   | TYPE    | INCLUSION
----------|--------|---------|----------
15        | Errata | erratum |          
14        | RPM    | rpm     | true     
----------|--------|---------|----------

And the filter information is:

hammer content-view filter info --id 15
Filter ID:    15
Name:         Errata
Type:         erratum
Inclusion:    false
Description:  Exclude Erratum after a cut-off date
Repositories: 

Rules:        
 1) ID:         10
    Start Date: 2018-12-06T22:00:00.000Z
    Types:      security, enhancement, bugfix
    Created:    2018/12/12 10:09:26
    Updated:    2018/12/12 10:12:52

But, then I ask for the list of the rules, I get nothing!

hammer content-view filter rule list --content-view-filter-id=15
--------|-----------|------|---------|-----------------|-----------------|--------------|-----------|------------|---------
RULE ID | FILTER ID | NAME | VERSION | MINIMUM VERSION | MAXIMUM VERSION | ARCHITECTURE | ERRATA ID | START DATE | END DATE
--------|-----------|------|---------|-----------------|-----------------|--------------|-----------|------------|---------

What am I doing wrong?

Hmm… this is certainly how you use these commands. It seems like you’re hitting a bug. What’s the output of rpm -qa foreman\|katello\|hammer
