Why do I get a 200 from a authentication-required request using expired access token with django rest framework simple jwt? - django-rest-framework-simplejwt

Question

I am building a REST API with DRF using djangorestframework-simplejwt(5.2.1)
When I try to access a protected endpoint which requires an authentication with an expired token, expecting a 401. Instead, I get a positive answer from the API every single time.
Here is the test view:
from rest_framework.decorators import permission_classes
from rest_framework.permissions import IsAuthenticated
#api_view(['GET'])
#permission_classes([IsAuthenticated])
def test(request:HttpRequest) -> Response:
return JsonResponse('OK')
Here is the urls.py:
from django.contrib import admin
from django.urls import path,include
from rest_framework_simplejwt.views import TokenRefreshView, TokenVerifyView
from account.views import AccountTokenObtainPairView
from base.views import test
urlpatterns = [
path('admin/', admin.site.urls),
path('api-auth/', include('rest_framework.urls')),
path('api/test/', test),
path('api/token/', AccountTokenObtainPairView.as_view(), name='token_obtain_pair'),
path('api/token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
path('api/token/verify/', TokenVerifyView.as_view(), name='token_verify'),
]
And here, the postman request with the result I got:
As last my settings.py :
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES':('rest_framework_simplejwt.authentication.JWTAuthentication',),
}
SIMPLE_JWT = {
'ACCESS_TOKEN_LIFETIME': timedelta(minutes=1),
'REFRESH_TOKEN_LIFETIME': timedelta(days=30),
'ROTATE_REFRESH_TOKENS': True,
'BLACKLIST_AFTER_ROTATION': True,
'UPDATE_LAST_LOGIN': False,
'ALGORITHM': 'HS256',
#'SIGNING_KEY': SECRET_KEY,
'VERIFYING_KEY': None,
'AUDIENCE': None,
'ISSUER': None,
'JWK_URL': None,
'LEEWAY': 0,
'AUTH_HEADER_TYPES': ('Bearer',),
'AUTH_HEADER_NAME': 'HTTP_AUTHORIZATION',
'USER_ID_FIELD': 'id',
'USER_ID_CLAIM': 'user_id',
'USER_AUTHENTICATION_RULE': 'rest_framework_simplejwt.authentication.default_user_authentication_rule',
'AUTH_TOKEN_CLASSES': ('rest_framework_simplejwt.tokens.AccessToken',),
'TOKEN_TYPE_CLAIM': 'token_type',
'TOKEN_USER_CLASS': 'rest_framework_simplejwt.models.TokenUser',
'JTI_CLAIM': 'jti',
'SLIDING_TOKEN_REFRESH_EXP_CLAIM': 'refresh_exp',
'SLIDING_TOKEN_LIFETIME': timedelta(minutes=5),
'SLIDING_TOKEN_REFRESH_LIFETIME': timedelta(days=1),
}
by calling /api/test/ I was expected django to send back an answer telling me that the request could not be fullfilled since the access token was expired.
I did check that the token is indeed expired:
Thank you for your help!
