Changing feedback status with email notification

There is an API controller CreateFeedbackAPIView that creates a Feedback object and then asynchronously starts the change_status_feedback task. The task updates the feedback status and calls the send_mail() function. Conduct a code review and identify syntax errors. Ensure that the code works correctly with the Celery task, serialization, and object saving.

@app.task(name='change_status_feedback')
def change_status_feedback(feedback):
    feedback.status = 'in_progress'
    send_mail()
    feedback.save()

class CreateFeedbackAPIView(APIView):
    def create(self, request):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        feedback = Feedback.objects.create(**serializer.validated_data)
        change_status_feedback.delay(feedback)
        return feedback
