In the tutorial, when creating the venv, the recommended version of django-graphql-jwt is 0.1.5. This throws some errors when following along with the Authentication bit of the tutorial. From the changelog, the graphene middleware was introduced in v0.2.0.

@BonfaceKilz Thanks for reporting the issue, and mentioning about the changelog. Upgrading django-graphql-jwt to v0.2.0, resolved the issue.

pip install django-graphql-jwt==0.2.0

While following the tutorial, I also installed django-graphql-jwt-0.1.5 (as it is mentioned).

In the autentication part, I started getting the middleware errors.

TypeError: __init__() missing 1 required positional argument: 'get_response'     

Tried to figure it out and answer suggested "it could be due to different settings variable for middleware in different django versions (MIDDLEWARE and MIDDLEWARE_CLASSES)". Made an update in graphe settings (from MIDDLEWARE TO MIDDLEWARE_CLASSES) and it worked. (haven't checked other impact)

GRAPHENE = {
    'SCHEMA': 'hackernews.schema.schema',
    'MIDDLEWARE': [
        'graphql_jwt.middleware.JSONWebTokenMiddleware',
    ]
}

However after checking this issue, I upgraded to pip install django-graphql-jwt==0.2.0 and everything works fine.

Please make an update in tutorial.
