Django Throttle on Test Server

Question

I am working on a project and i am using django restframework throttle it works well when using the server either on local or production but when i tries testing the endpoint using testcase it returns an error

This is my configurations

the default rest framework setting

REST_FRAMEWORK = {

'DEFAULT_THROTTLE_CLASSES': [
    'rest_framework.throttling.AnonRateThrottle',
    'rest_framework.throttling.UserRateThrottle',
    'rest_framework.throttling.ScopedRateThrottle',
],
'DEFAULT_THROTTLE_RATES': {
   
    'anon': '100/min',
    'user': '200/min',
    # the throttle is the amount of time a user can access a route in a minute
    'authentication': '3/min',
    # used on route where the user is not logged in like requesting otp
    'monitor': '3/min',
},
'DEFAULT_AUTHENTICATION_CLASSES': (
    # currently setting the default authentication for django rest framework to jwt
    'rest_framework_simplejwt.authentication.JWTAuthentication',
),
'DEFAULT_PERMISSION_CLASSES': (

    'rest_framework.permissions.IsAuthenticatedOrReadOnly',
),
'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema',

}

The test case

def test_verify_and_check_if_profile_created(self):
    """
    This test if the user profile was created,
    and also it verify the user first
    :return:
    """
    #  checks if the user profile is not none
    self.assertIsNotNone(self.user.user_profile)
    #  request otp for the set-up user
    client = APIClient()
    client.credentials(HTTP_INSTASAW_SK_HEADER=config('INSTASAW_SK_HEADER'))
    request_otp_response = client.post('/api/v1/auth/verify_account/', {
        "email": self.user_email,
    })
    print(request_otp_response.json())

The error

django.core.exceptions.ImproperlyConfigured: No default throttle rate set for 'anon' scope
