Comment 2 for bug 1809218

adding a note because this is super confusing to debug.

In the console you can see failing tempest but nothing earlier e.g. in https://review.openstack.org/#/c/625256/ (promotion blocker for bug #1808349 in both container-multinode and standalone, failed tempest [1][2] but you have to go looking in errors.txt [3] to find the bug here like
