We see the following errors when using nested lists:
Error: Decorated type deeper than introspection query.

Here's the example code that can cause this issue. Graphene introspection doesn't report any errors.
import graphene, json
class Animal(graphene.Interface):
id = graphene.String()
class Dog(graphene.ObjectType):
class Meta:
interfaces = (Animal, )
breed = graphene.String()
class Cat(graphene.ObjectType):
class Meta:
interfaces = (Animal, )
category = graphene.String()
class Query(graphene.ObjectType):
animals = graphene.NonNull(graphene.List(graphene.NonNull(graphene.List(graphene.NonNull(Animal)))))
def resolve_animals(self, args, context, info):
return[[Dog(id=1, breed='Golden Retriever'),
Dog(id=2, breed='German Shepard')],
[Cat(id=11, category ='Tiger'),
Cat(id=12, category='House Cat')]]
schema = graphene.Schema(query=Query, types=[Dog, Cat, ])
Errors disappear if we remove the "required" or NonNull decorators. Any suggestions on how to fix these errors?

issue appears to be due to graphiql version set to 0.7.1 in render_graphiql.py - I was able to fix the issue by changing this to 0.10.1 in my local copy.
