Expected type 'GraphQLObjectType', got 'Type[Query]' instead

Hello.

Django 2.0.7, Python 3.6.1

I get some strange warning at PyCharm 2018.2:

Expected type ‘GraphQLObjectType’, got ‘Type[Query]’ instead …

Inspection info: This inspection detects type errors in function call expressions. Due to dynamic dispatch and duck typing, this is possible in a limited but useful number of cases. Types of function parameters can be specified in docstrings or in Python 3 function annotations.

But everything is working great!

# core/schema.py

import graphene
from projects.schema import Query as ProjectQuery

class Query(ProjectQuery, graphene.ObjectType):
    pass

schema = graphene.Schema(query=Query)

# projects/schema.py

import graphene
from graphene_django.types import DjangoObjectType
from .models import Project

class ProjectType(DjangoObjectType):
    class Meta:
        model = Project
        interfaces = (graphene.Node,)

class Query(graphene.ObjectType):
    all_projects = graphene.List(ProjectType)

    def resolve_all_projects(self, info, **kwargs):
        return Project.objects.all()

What’s wrong? How to solve it? Thanks!

2019.3 still has this warning issue. schema = graphene.Schema(query=Query, mutation=Mutation) Expected type ‘ObjectType’, got ‘Type[Query]’ instead Strange enough only Query does it, the Mutation type is ok.

The types: class Query(graphene.ObjectType): actor = graphene.Field(ActorType, id=graphene.Int()) movie = graphene.Field(MovieType, id=graphene.Int()) actors = graphene.List(ActorType) movies = graphene.List(MovieType) …methods are removed for brevity.

class Mutation(graphene.ObjectType): create_actor = CreateActor.Field() update_actor = UpdateActor.Field() create_movie = CreateMovie.Field() update_movie = UpdateMovie.Field()

@jayhale the codes still run, and yes, it is just a warning message from PyCharm.

P.S. problem still exists in the latest PyCharm 2018.2
