Ansible Plugin

I run the ansible playbooks from pulp-installer 3.12.2 (also once with the latest commit of the master branch) on a fresh CentOS 8 as I did last week but suddenly it breaks on database migration with the error:

File \"/usr/local/lib/pulp/lib64/python3.6/site-packages/click/core.py\", line 2108, in __init__", "    ) from None", "ValueError: 'default' must be a list when 'multiple' is true."], "stdout": "", "stdout_lines": []}

Is the click package incompatible? I really don't know now which version of the pulp-installer really works, cause on every rerun of the playbooks another issue appears mostly due to 3rd party incompatibilities (also django upgrade recently broke the installation) . Would it somehow possible to fix all this dependencies somewhere (which file?) cause when I check out 3.12.2 I always expect the same result? Or is there something I do wrong?
