Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:


Version-Release number of selected component (if applicable):
Satellite 6.10.0 Snap 7.0

How reproducible:
always

Steps to Reproduce:
1. # hammer host errata apply --host-id <host-id>
This command uses katello agent and will be removed in favor of remote execution in a future release.
The remote execution equivalent is `hammer job-invocation create --feature katello_errata_install`.
Could not apply errata:
  no implicit conversion of nil into String
2. # echo $?
70


Actual results:
no implicit conversion of nil into String

Expected results:
A warning should exist to pass errata_ids, like when not passing --errata to command `hammer host-collection erratum install --id 1 --organization-id 1`

Additional info:
On Satellite 6.9.3 Snap 5.0 
# hammer host errata apply --host-id 3
Could not apply errata:
  undefined method `[]' for nil:NilClass
