Could not import 'smvc.schema.schema' for Graphene setting 'SCHEMA'. AttributeError: module 'graphene' has no attribute 'AbstractType'.

[msomali]

I'm trying to setup JWT Authorization with Graphene but I get this error Could not import 'smvc.schema.schema' for Graphene setting 'SCHEMA'. AttributeError: module 'graphene' has no attribute 'AbstractType'. when I try test it on GraphiQL and Insomnia. Is AbstractType no longer included in Graphene?

This error occurs when I do a query for authorizing a user to login with JWT using Insomnia, the headers are in place Content-Type and Authorization (as instructed here on the tutorial https://www.howtographql.com/graphql-python/4-authentication/ or here on git repo https://github.com/howtographql/howtographql/blob/master/content/backend/graphql-python/4-authentication.md) but it won't login the user. I have django admin user and normal user, they bring same error.

from django.contrib.auth import get_user_model

    class Meta:

    me = graphene.Field(UserType)
    users = graphene.List(UserType)

    def resolve_users(self, info):
        return get_user_model().objects.all()

    def resolve_me(self, info):
        user = info.context.user
        if user.is_anonymous:
            raise Exception('Not logged in!')

        return user

    user = graphene.Field(UserType)

    class Arguments:
        username = graphene.String(required=True)
        password = graphene.String(required=True)
        email = graphene.String(required=True)

    def mutate(self, info, username, password, email):
        user = get_user_model() (
            username=username,
            email=email,
        )

        user.save()

        return CreateUser(user=user)

class Mutation(graphene.ObjectType):

If anyone has a way around to resolve or go around this error, I'll appreciate your help.

@msomali you are using pre relase version of graphene, please switch to v2 to use AbstractType.
As you can see here, there is abstracttype defined in v2 but if you switch to latest version, v3, then there is no abstracttype defined there yet, v3 is in dev phase.

@msomali more-ever it is always good to use same version of dependencies as used by tutorials. You can find here the dependencies versions of this tutorial.

Hi @s-mrb I tried to downgrade graphene to v2 but I could not restart the server back. I'm thinking of starting a new project and copy some of the work that have already been done on the current broken project.

Thanks.

@s-mrb so I decided to start a fresh project but still stuck on authentication with JWT as this time I cannot query the logged in user even though I'm following every step of the tutorial including mutating the tokenAuth and use it with Authorization HTTP header (Authorization: JWT ) with Insomnia. Other settings are in place including middleware and authentication_backends.

Error I get:

This is for anyone using graphene 3 or later and encounter the error while following the tutorial. AttributeError: module 'graphene' has no attribute 'AbstractType'

Update your code with
class Query(graphene.ObjectType, abstract=True):
instead of
class Query(graphene.AbstractType):

AbstractType is deprecated in version 3 and later of graphene.
