RPM Publication fails with "unexpected keyword argument 'main_variant'" error
Description
We are using pulp to create and host a package repository for networks that are not connected to the internet.
In the past week our packer build process began to fail when we attempt to create an RPM Publication. The publication process fails with the following error:

I believe the root cause of the issue is a change to the productmd package.
My latest working pulp build has productmd 1.32, while the broken one has productmd 1.33.
If you look at the changes, they are explicitly adding the main_variant parameter to treeinfo: https://github.com/release-engineering/productmd/commit/06ab7b7593ce21b20b75c25d72c9aafb67155fd1

I was able to get around the issue by manually editing roles/pulp_common/templates/pip_constraints_for_plugins.txt.j2
bash-4.2$ cat roles/pulp_common/templates/pip_constraints_for_plugins.txt.j2
pulpcore=={{ pip_pkgs.packages[pulp_install_dir + '/bin/pip'].pulpcore[0].version }}
productmd==1.32
bash-4.2$
This resulted in a rendered file as follows:
[root@dark-aster-registry ~]# cat /usr/local/lib/pulp/pip_constraints_for_plugins.txt
pulpcore==3.12.0
productmd==1.32
[root@dark-aster-registry ~]#
which forced the older version:
[root@dark-aster-registry ~]# . /usr/local/lib/pulp/
bin/ pip-selfcheck.json
include/ pyvenv.cfg
lib/ requirements.in
lib64/ share/
pip_constraints_for_plugins.txt
[root@dark-aster-registry ~]# . /usr/local/lib/pulp/bin/activate
(pulp) [root@dark-aster-registry ~]# pip list | grep productmd
productmd 1.32
(pulp) [root@dark-aster-registry ~]#

- Status changed from NEW to CLOSED - DUPLICATE
The workaround is to downgrade to productmd 1.32.
The compatibility with 1.33 will be in the upcoming pulp_rpm 3.13 release. See #8807.
