Cannot use an enum as a graphene.List named argument

[spacether]

When defining this query:

class Episode(graphene.Enum):
    NEWHOPE = 4
    EMPIRE = 5
    JEDI = 6

class ListAvailableSubscriptionPlans(graphene.ObjectType):

    available_subscription_plans = graphene.List(
        graphene.NonNull(graphql.SubscriptionPlanObject),
        subscriber_id=graphene.Int(required=True),
        subscriber_type=Episode,
        target_currency=graphene.String(required=True),
    )

    def resolve_available_subscription_plans(
        self, info, subscriber_id, subscriber_type, target_currency
    ):

And running the python module, we get the error:

  File "/app/subscription_management/subscriptions/api.py", line 16, in <module>
    class ListAvailableSubscriptionPlans(graphene.ObjectType):
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/utils/subclass_with_meta.py", line 52, in __init_subclass__
    super_class.__init_subclass_with_meta__(**options)
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/objecttype.py", line 112, in __init_subclass_with_meta__
    fields.update(yank_fields_from_attrs(base.__dict__, _as=Field))
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/utils.py", line 31, in yank_fields_from_attrs
    field = get_field_as(value, _as)
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/utils.py", line 21, in get_field_as
    return _as.mounted(value)
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/mountedtype.py", line 15, in mounted
    return cls(
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/field.py", line 103, in __init__
    self.args = to_arguments(args or OrderedDict(), extra_args)
  File "/app/virtualenv/lib/python3.8/site-packages/graphene/types/argument.py", line 80, in to_arguments
    extra_args = sorted(extra_args.items(), key=lambda f: f[1])
TypeError: '<' not supported between instances of 'EnumMeta' and 'Int'

Because this line does not work:
subscriber_type=Episode

[spacether]

A work around is to cast the enum as a graphene.Argument:
subscriber_type=graphene.Argument(Episode)

class ListAvailableSubscriptionPlans(graphene.ObjectType):

    available_subscription_plans = graphene.List(
        graphene.NonNull(graphql.SubscriptionPlanObject),
        subscriber_id=graphene.Int(required=True),
        subscriber_type=graphene.Argument(Episode),
        target_currency=graphene.String(required=True),
    )

no

You need to call Episode like with other GraphQL types.

subscriber_type=Episode()
