Foreman-nightly-rpm-pipeline 469 failed

Foreman nightly pipeline failed:

The mash seems to be failing with:

Traceback (most recent call last):

I have seen something like this before, and I am trying to dig back through my memory as to why the mash generation fails here.

I untagged the most recent foreman nightly build and mash was OK:
