role fails with "Invalid data passed to 'loop'"

TASK [stackhpc.libvirt-host : Ensure configuration files exist] ********************************************************************************************************** task path: /home/birger/.ansible/roles/stackhpc.libvirt-host/tasks/config.yml:24 fatal: [examplehost]: FAILED! => { "msg": "Invalid data passed to 'loop', it requires a list, got this instead: <generator object select_or_reject at 0x7f2bcc663f40>. Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup." }

I used the role t2d.ansible_role_libvirt_host (which is v. 1.4.1 of this same project?) without this problem. It had other problems, though. So I tried to switch over here. Same playbook now gives this error.

I got around this by appending | list to a bunch of loops. I didn't even try to understand the existing stuff, just forced everything that triggered errors to become lists. Now everything seems to work, including the stuff that did not work in t2d.ansible_role_libvirt_host. Now on to find out why the vm only starts with selinux in permissive mode.
