Pulp

I don't think this is easily reproducible, but we saw this error in our nightly pipeline after upgrading to 3.14 (although it may be unrelated).

python3-pulp-rpm-3.13.3-1.el8.noarch python3-pulpcore-3.14.1-1.el8.noarch

This was also a pulp3 <-> pulp3 sync, all running the same pulpcore and pulp-rpm versions.
