Fresh install of Foreman Katello nightly - pulpcore errors

Problem:
Following the install procedure from Installing Foreman nightly server with Katello nightly plugin on Enterprise Linux i installed Foreman nightly server with Katello nightly plugin on a new server running CentOS 8 (fully updated).
However, there are errors during the install phase.
Not sure how serious these errors are, but i’m unable to sync the repositories later on (another error).

Expected outcome:
No errors during the install.

Foreman and Proxy versions:
Foreman 3.1.0
Katello 4.3.0
RPM package: foreman-installer-katello-1:3.1.0-0.1.develop

Foreman and Proxy plugin versions:
Foreman 3.1.0
