Django rest framework, how to properly update a list of something?

Question

React

Good morning, sending data from the front

export function addProject(typeProject) {

    axios.post("http://127.0.0.1:8000/add_project/", {
        userId: window.localStorage.getItem("userId"),
        typeProject: typeProject
    })
        .then(res => {
            console.log(res);
        })
        .catch(error => {
            console.log(error)
        });
}


route
router.register(r'add_project', AddProjectView)


views
class AddProjectView(mixins.CreateModelMixin, mixins.RetrieveModelMixin,
                     mixins.UpdateModelMixin, viewsets.GenericViewSet):
    queryset = Project.objects.all()
    serializer_class = ProjectSerializer
    authentication_classes = (TokenAuthentication,)

    def put(self, request):
        """Create project."""
        instance = self.queryset
        return self.update(request, instance=instance)

serializer
class ProjectSerializer(serializers.ModelSerializer):

    class Meta:
        model = Project
        fields = ('name', 'projecttype')

    def update(self, instance, validated_data):
        """
        Create the object.
        :param instance:
        :param validated_data: string
        """
        user_id = validated_data["userId"]
        user = User.objects.get(id=user_id)
        print(user)
        user_account = UserAccount.objects.get(user=user)
        customer = Customer.objects.get(useraccount=user_account)
        instance.customer = customer
        instance.name = "PROJECT 001"
        instance.projecttype = validated_data["typeProject"]
        instance.save()

        return instance

Everything seems to be clear, but it does not work. Returns an error 400. Tell me where the error is

Check ALLOWED_HOSTS = ['*'] in settings.py and

CORS_ORIGIN_WHITELIST = (
 ‘localhost:8080’,
)
