Error Using Graphene Django with Polymorphic (typed models)

See original GitHub issue

I am trying to query a field source on a model called Requirement which can have a source which is a pool however pool is polymorphic. That is, it is a typed model.

Pool(TypedModel):
   ...

ManufacturedLabwarePool(Pool):
  ...

When I try to query source as a field on Requirement I get the following error:

I’m not sure how to resolve this so that we do not expect a specific type for a given field.
