Question: I'm following the graphql python tutorial at https://www.howtographql.com/graphql-python/4-authentication/. It worked fine for the first 3 sections, but in the Authentication section I've run into this problem. I am learning python, don't know Django or graphql, so it's a lot to digest all at once, but it was going ok until now. Also not sure what relevant bits to include here. I followed all the instructions. When I go to my local project site at localhost:8000/graphql/, I get  TypeError at /graphql/ __init__() missing 1 required positional argument: 'get_response' Here is the relevant snippet of my settings.py: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', ] GRAPHENE = { 'SCHEMA': 'hackernews.schema.schema', 'MIDDLEWARE': ['graphql_jwt.middleware.JSONWebTokenMiddleware', ], } AUTHENTICATION_BACKENDS = [ 'graphql_jwt.backends.JSONWebTokenBackend', 'django.contrib.auth.backends.ModelBackend', ]  I also did import graphql_jwt in my main schema.py  Here is some kind of stack trace Environment: Request Method: GET Request URL: http://localhost:8000/graphql/ Django Version: 2.1.4 Python Version: 3.7.4 Installed Applications: ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'graphene_django', 'links'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware'] Traceback: File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\django\core\handlers\exception.py" in inner 34. response = get_response(request) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\django\core\handlers\base.py" in _get_response 126. response = self.process_exception_by_middleware(e, request) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\django\core\handlers\base.py" in _get_response 124. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\django\views\decorators\csrf.py" in wrapped_view 54. return view_func(*args, **kwargs) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\django\views\generic\base.py" in view 62. self = cls(**initkwargs) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\graphene_django\views.py" in __init__ 88. self.middleware = list(instantiate_middleware(middleware)) File "C:\Users\e79909\projects\python\graphql-python\venv\lib\site-packages\graphene_django\views.py" in instantiate_middleware 48. yield middleware() Exception Type: TypeError at /graphql/ Exception Value: __init__() missing 1 required positional argument: 'get_response' 

Answer: Ok, I just found it.  GRAPHENE = { 'SCHEMA': 'hackernews.schema.schema', 'MIDDLEWARES': ['graphql_jwt.middleware.JSONWebTokenMiddleware'], }  Notice the S. It needs to be 'MIDDLEWARES', not 'MIDDLEWARE'.  Found the solution on this GitHub issue Also, according to this comment on the same issue, you should add 'graphql_jwt.middleware.JSONWebTokenMiddleware' to the MIDDLEWARE list (the one with all the Django middleware). MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'graphql_jwt.middleware.JSONWebTokenMiddleware', ### <---Add this line 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ]
