How can I fix the issue of objects being stored twice in Django database?

I am using the YouTube Data API to create an object, but when I create a single object, it creates two objects - one with the proper details and one that is blank. How can I resolve this issue?

before creating object

after creating single object

I am trying with the following code.view.py

class VideoCreateView(CreateView):    model = Video    form_class = VideoForm    template_name = "videos/video_form.html"    def form_valid(self, form):        video = Video()        video.url = form.cleaned_data['url']        parse = urllib.parse.urlparse(video.url)        video_id = urllib.parse.parse_qs(parse.query).get('v')        if video_id:            video.youtube_id =video_id[0]            response = requests.get(f'https://youtube.googleapis.com/youtube/v3/videos?part=snippet&id={video_id[0]}&key={YOUTUBE_API_KEY}')            json = response.json()            items = json["items"]            assert len(items) <= 1            if len(items):                title = items[0]["snippet"]["title"]                video.title = title                video.save()            else:                title = "N/A"        return super().form_valid(form)

models.py

class Video(models.Model):    title = models.CharField(max_length=255)    url = models.URLField()    youtube_id = models.CharField(max_length=255)    slug = models.SlugField(blank=True)    def __str__(self):        return self.title    def get_absolute_url(self):        return reverse("videos:video_detail", kwargs={"slug":self.slug})def video_pre_save_reciever(sender,instance,*args, **kwargs):    if not instance.slug:        instance.slug = unique_slug_generator(instance)pre_save.connect(video_pre_save_reciever,Video)

if more code is require than tell me in comment , i will update my question with that information.
