Syncing CentOS8 kickstart on Leap 15.2 fails on treeinfo not found.

Hello all, is syncing a CentOS 8 kickstart tree (or syncing kickstart trees in general) supported on SUSE Leap 15.2 with Uyuni master? I could not find the reference to the kickstart sync function in the documentation. Running reposync on http://msync.centos.org/centos/8/BaseOS/x86_64/os/ gives me this error: # /usr/bin/spacewalk-repo-sync --channel centos8-baseos-x86_64 --type yum --non-interactive --sync-kickstart 08:09:43 ====================================== 08:09:43 | Channel: centos8-baseos-x86_64 08:09:43 ====================================== 08:09:43 Sync of channel started.
