Description

As a platform administrator, I want to modify the group of one of my users, but I get an error when accessing the place where I'm supposed to be able to do so, i.e. :

Settings > Security > [an organization for which I'm admin] > [a user belonging to this organization] > the pen at bottom right to modify the user > the "Group" tab in the side panel that just opened

--> Error occurs
