Cannot publish new content view version

When publishing a new content view version, the error :ERF12-3113 Unable to detect puppet path is thrown. The new version is not published.
Expected outcome:
A new version.
Foreman and Proxy versions:
Foreman and foreman-proxy1.20.1, Katello 3.10
Foreman and Proxy plugin versions:
pupl-puppet 2.17
Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]
(for logs, surround with three back-ticks to get proper formatting, e.g.)
System is in a dark environment and logs are tedious to extract. If necessary, please request.
