FIeldError at /icl/group/1/members/

[AdrianDAlessandro]

Ok, I managed to work out I need to navigate to http://127.0.0.1:8000/icl/group/1/members/ and it worked for when I wasn't a PI. But after setting is_pi to True it failed with this error (I believe the same error mypy was showing):

...
  File "/usr/src/imperial_coldfront_plugin/imperial_coldfront_plugin/views.py", line 51, in group_members_view
    group_members = GroupMembership.objects.filter(owner=user)
...
FieldError at /icl/group/1/members/
Cannot resolve keyword 'owner' into field. Choices > are: group, group_id, id, member, member_id
