Bug: Visualisations tab throws "Call to a member function map() on null" in a community install

I am not sure if this is just a community issue but if I do the following:

  1. Navigate to Settings > Access Management > Groups and click on your target group.
  2. Go to the Visualizations tab.

I receive the message in red “Call to a member function map() on null”

I would expect to be able to see the group or some other details to set the visualisation for the group.
