The workaround would be to register a custom handler: https://github.com/graphql-python/graphene-django/issues/18#issuecomment-253549577

But as this is now part of Django, it should be added.

The Django Postgres array field handler is already implemented.

The Mongodb arrayfield is not part of Django (it's in Djongo)... so I would say that implementing a custom handler is the solution (and honestly you can most likely use the same handler as the postgres arrayfield one)
