Found different types with the same name in the schema: ErrorType, ErrorType.

[KINGH242]

I have installed django-graphql-auth with the latest version of graphene-django, but I get the above error because of duplicate types with the same name. ErrorType in graphql_auth/types.py clashes with ErrorType in graphene_django/types.py. I want to use this package in a project, but this here is blocking me.

[PedroBern]

Please print the error traceback.

[KINGH242]

graphql-python/graphene-django#539 (comment) maybe related.

[PedroBern]

To investigate further I will need the steps to reproduce it, but I don't see the graphql_auth in the traceback, it's probably more a graphene_django issue. Did manage to complete the quickstart? Do you get this error if you uninstall graphql_auth?

[KINGH242]

If I uninstall graphql_auth or remove the mutations from the schema, the error goes away. It seems to be because of the ErrorType class, which is the same name as the ErrorType class for graphene_django. When graphene runs its reducer function, it crashes because it finds two classes in the schema which have the same name....the ErrorType class.
This is what the output of pip freeze

[PedroBern]

I've just released the 0.3.4 version, try it :) You can see it here. Now it's probably fixed, please let me know if you keep experiencing the issue again, so I reopen it.

[KINGH242]

I have just tested 0.3.4 out in my project and it works fine now.

Thanks much for the update. The effort is appreciated.
