Django OAuth Toolkit giving me "Authentication credentials were not provided" error

Question

I've been trying for a while to get django Oauth toolkit to work but no matter what I get a 401 error and when I check the details it's the error in the title. Even though I'm obviously passing credentials

views.py:

class PostCarFax(viewsets.ModelViewSet):

    #authentication_classes = [authentication.TokenAuthentication, authentication.SessionAuthentication, authentication.BaseAuthentication]
    permission_classes = [permissions.IsAuthenticated, TokenHasReadWriteScope]
    queryset = CarFax.objects.all()
    serializer_class = CarFaxSerializer

serializers.py:

class CarFaxSerializer(serializers.ModelSerializer):

    class Meta:
        model = CarFax
        fields = ('vin', 'structural_damage', 'total_loss',
                  'accident', 'airbags', 'odometer', 'recalls',
                  'last_updated', 'origin_country')

    def create(self, validated_data):
        return CarFax.objects.create(**validated_data)

    data = {

    }

    data = json.dumps(data)
    response = requests.post('http://127.0.0.1:8000/api/v1/post_carfax/', headers=headers, data=data)
    # print(json.dumps(response.json))
    return response.text

I've tried playing around with the settings a lot, I am not sure what I should do. The credentials are being passes right there in the headers, I am not sure why it's saying they don't exist

Fixed it for anyone in the future

I just need to use path() like the tutorial used instead of url(). I didn't use it because on IntelliJ it was underlined and gave me an unresolved error

Add the following code to your settings.py file:

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'oauth2_provider.contrib.rest_framework.OAuth2Authentication',
    )
}
