Filter class filtering broken with django-filter 2.0

While using any of the examples [listed here](https://docs.graphene-python.org/projects/django/en/latest/filtering/#custom-filtersets), this error is thrown by `django-filter`:

AssertionError: The `lookup_expr` argument no longer accepts `None` or a list of expressions. Use the `LookupChoiceFilter` instead. See: https://django-filter.readthedocs.io/en/master/guide/migration.html

Then if I, as they suggest, change `lookup_exp` to use `LookupChoiceFilter` instead. Like so:

class UserFilter(django_filters.FilterSet):
name = django_filters.LookupChoiceFilter(
field_class=forms.CharField,
lookup_choices=[
('exact', 'Equals'),
]
)
class Meta:
model = User
fields = ['name']

Then my `name` filter shows up as `name` in the schema instead of expected `name_Exact`. GraphQL allows me to pass the `name` parameter, but as expected no filtering is done.
