Undefined method 'mass_update_expiry'

I’m attempting to get discovery working and after manually installing it, I’m seeing the below error in the /var/log/foreman/production.log when my target system tries to report in and I’m not sure what step I might’ve missed.

I did a manual install of the discovery module per the online instructions, restarted httpd, restarted foreman.service, but still no joy and I’m not sure where to troubleshoot next.

I’m on a custom build of Foreman (patched to allow me to continue using our existing Puppet 7 servers and infrastructure).
