Graphene-django: Ordering filter in foreign key sets missing

[samkit-jain]

import django_filters
import graphene
from graphene_django import DjangoObjectType
from graphene_django.filter import DjangoFilterConnectionField

from api.models import Children, Parent


class ParentNode(DjangoObjectType):
    class Meta:
        model = Parent
        filter_fields = ["parent_id"]
        interfaces = (graphene.relay.Node,)


class ChildrenNode(DjangoObjectType):
    class Meta:
        model = Children
        filter_fields = ["name", "parent__parent_id"]
        interfaces = (graphene.relay.Node,)


class ParentFilter(django_filters.FilterSet):
    parent_id = django_filters.CharFilter(lookup_expr="iexact")

    class Meta:
        model = Parent
        fields = ["parent_id"]

    order_by = django_filters.OrderingFilter(fields=(("created_at", "created_at"), ("updated_at", "updated_at"),))


class ChildrenFilter(django_filters.FilterSet):
    name = django_filters.CharFilter(lookup_expr="icontains")
    parent__parent_id = django_filters.CharFilter(lookup_expr="iexact")

    class Meta:
        model = Children
        fields = ["name", "parent__parent_id"]

    order_by = django_filters.OrderingFilter(fields=(("created_at", "created_at"), ("updated_at", "updated_at"),))


class Query(object):
    parents = graphene.relay.Node.Field(ParentNode)
    all_parents = DjangoFilterConnectionField(ParentNode, filterset_class=ParentFilter)

    children = graphene.relay.Node.Field(ChildrenNode)
    all_children = DjangoFilterConnectionField(ChildrenNode, filterset_class=ChildrenFilter)

Here, the Children table is having the Parent as the foreign key. When querying allChildren in the GraphQL like

query {
  allChildren(orderBy: "-created_at") {
    edges {
      node {
        name
        parentsSet {
          edges {
            node {
                parentId
            }
          }
        }
      }
    }
  }
}

the parentsSet NodeConnection contains before, after, first, last and parentId as the valid filter fields. Why is it missing the orderBy field and how can it be added to it?
