Problem with creating ISO "isohybrid: .... unable to find efi image"

Problem:
I installed a new Foreman version 2.5.2 on a Debian 10 to replace our old Foreman 1.23.2 on Centos. We use bootdisk to install VMs. This worked fine on the old system.
The problem is that this unfortunately does not run on the new Foreman.

The installation settings in the foreman-installer have been taken over manually.

When creating a VM, the following error appears:

The error on the command line:

root@****:~# foreman-rake bootdisk:generate:generic --trace

Use genisoimage -help
to get a list of valid options.

After some searching I found the following “solution” for this:
