Hello, thanks, you are right I changed the value in line 129 of /usr/lib/python3/dist-packages/muranodashboard/catalog/views.py from if not http_utils.is_safe_url(url=redirect_to, host=request.get_host()): to if not http_utils.is_safe_url(url=redirect_to, allowed_hosts=request.get_host()): and now it works.

"host" argument of is_safe_url() was deprecated in Django 1.11 and dropped in Django 2.1. Horizon switches to use Django 2.2 in Ussuri release, so perhaps murano-dashboard (at least the feature mentioned) does not work since Ussuri release. The fix would be to replace host=xxxx with allows_hosts=[xxxx]. Thanks, Akihiro Motoki (irc: amotoki) On Fri, Feb 19, 2021 at 5:18 AM Bujack, Stefan <stefan.bujack@desy.de> wrote:

Hello,

we have an openstack victoria deployment on ubuntu 20.04.

We use the murano-dashboard in horizon.

When clicking on add component in APP Catalog --> Applications --> Environments

we get an error page and apache2 has an error:
