Auth0 LOGIN URL 404 Not found

Reposting from https://community.auth0.com/t/login-url-404-not-found/52181

Ive setup an auth0 app. I am trying to setup an auth webapp flow and code authorization flow as well;

I am following this article: https://auth0.com/docs/quickstart/webapp/django to implement Auth0 web app flow.

To implement backend code authorization flow im following: https://auth0.com/docs/quickstart/backend/django

Implementations are in this file: apps/auth_zero/auth0backend.py to write both the standard web app flow and the code authorization flow. which subroutes /login/auth0 as auth0/login/auth0; check the main app urls.

But I get 404 not found when i Press Login: Ive setup an auth0 app. I am trying to setup an auth webapp flow and code authorization flow as well;

I suspect something must be wrong in my settings;

The repo for ref is: https://github.com/Xcov19/covidX/tree/1777fe574c640c31db587e361c32758bc0c175d2/covidX

this is my middleware:

MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    # Map username from the Access Token payload to
    # Django authentication system
    "django.contrib.auth.middleware.RemoteUserMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
]

These are my backend and auth0 jwt configs:

# SOCIAL AUTH AUTH0 BACKEND CONFIG
SOCIAL_AUTH_TRAILING_SLASH = os.getenv("SOCIAL_AUTH_TRAILING_SLASH")
SOCIAL_AUTH_AUTH0_KEY = os.environ.get("SOCIAL_AUTH_AUTH0_KEY")
SOCIAL_AUTH_AUTH0_SECRET = os.environ.get("SOCIAL_AUTH_AUTH0_SECRET")
SOCIAL_AUTH_AUTH0_SCOPE = ["openid", "profile", "email"]
SOCIAL_AUTH_AUTH0_DOMAIN = os.environ.get("SOCIAL_AUTH_AUTH0_DOMAIN")
SOCIAL_AUTH_ACCESS_TOKEN_METHOD = os.getenv("ACCESS_TOKEN_METHOD")
JWT_AUDIENCE = os.getenv("JWT_AUDIENCE")

if AUDIENCE := (
    os.getenv("AUTH0_AUDIENCE") or f"https://{SOCIAL_AUTH_AUTH0_DOMAIN}/userinfo"
):
    SOCIAL_AUTH_AUTH0_AUTH_EXTRA_ARGUMENTS = {"audience": AUDIENCE}

# Set JWT_AUDIENCE to API identifier and the JWT_ISSUER to Auth0 domain
JWT_AUTH = {
    "JWT_PAYLOAD_GET_USERNAME_HANDLER": (
        "apps.auth_zero.auth0backend." "jwt_get_username_from_payload_handler"
    ),
    "JWT_DECODE_HANDLER": "apps.auth_zero.auth0backend.jwt_decode_token",
    "JWT_ALGORITHM": "RS256",
    "JWT_AUDIENCE": JWT_AUDIENCE,
    "JWT_ISSUER": "https://dev-mavl72j2.eu.auth0.com/",
    "JWT_AUTH_HEADER_PREFIX": "Bearer",
}

AUTHENTICATION_BACKENDS = {
    "apps.auth_zero.auth0backend.Auth0",
    "django.contrib.auth.backends.ModelBackend",
    "django.contrib.auth.backends.RemoteUserBackend",
    "guardian.backends.ObjectPermissionBackend",
}


LOGIN_URL = "/auth0/login/auth0"
LOGIN_REDIRECT_URL = "/"
AUTH_REDIRECT_URI = "/auth0/complete/auth0"

Im using drf, its settings are:

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    "DEFAULT_PERMISSION_CLASSES": [
        "rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly",
        "rest_framework.permissions.AllowAny",
    ],
    "DEFAULT_AUTHENTICATION_CLASSES": (
        "rest_framework_jwt.authentication.JSONWebTokenAuthentication",
        "rest_framework.authentication.SessionAuthentication",
        "rest_framework.authentication.BasicAuthentication",
    ),
    "DEFAULT_RENDERER_CLASSES": [
        "rest_framework.renderers.BrowsableAPIRenderer",
        "rest_framework.renderers.JSONOpenAPIRenderer",
    ],
}

Your problem is that you have an end-of-line marker in your re_path, so it won't match and delegate to the auth0 urls:

re_path(r"^auth0/?$", include("apps.auth_zero.urls")),

Does not match /auth0/something, only /auth0/ or /auth0. Loose the end of line marker.
