  message: >-
    Django REST framework configuration is missing default rate-
    limiting options. This could inadvertently allow resource
    starvation or Denial of Service (DoS) attacks. Add
    'DEFAULT_THROTTLE_CLASSES' and 'DEFAULT_THROTTLE_RATES'
    to add rate-limiting to your application.
