Per object checks on List/Create methods fail with 'pk' required

[nhi-vanye]

I have a policy that controls who can create of list objects

{
            "action": ["<method:get>"],
            "principal": "*",
            "effect": "allow",
            "condition_expression": ["(user_is_assessor or user_is_target or user_is_requestor or user_is_hr)"]
}

Where user_is_assessor is

    def user_is_assessor(self, request, view, action) -> bool:
        obj = view.get_object()
        return obj.assessor.user.username == request.user.username

(The goal being to check the "owner" of the object (assessor) is listing/creating child objects.

view.get_object() is throwing an error that I haven't supplied a pk

(AssertionError: Expected view AssessmentListView to be called with a URL keyword argument named "pk". Fix your URL conf, or set the .lookup_field attribute on the view correctly.)

Which is correct as this is a list view not a detail view.

(I'm using generics hence the use of `method:get' rather that 'list')
