NoReverseMatch at /videos/list/ Reverse for 'list_videos' not found. 'list_videos' is not a valid view function or pattern name

Well I am trying to create a Playlist quite similar with YouTube. But the Playlist can only create by superuser from admin panel and other user can only see that playlist and the videos within the playlist. When I thought that I am done than suddenly this error occured. I don't know where I am making mistake. Please help me to fix this problem.

videos/models.py

class VideosList(models.Model):

    list_title = models.CharField(max_length=255)
    list_cover = models.ImageField(upload_to='list cover', height_field=None, width_field=None, max_length=None,blank =True)
    create_date = models.DateField(default = timezone.now)

    def __str__(self):
        return self.list_title

class VideosModel(models.Model):

    
    videos_lists = models.ForeignKey(VideosList,on_delete=models.CASCADE) 
    video_title = models.CharField(max_length=250)
    video_url = models.URLField(max_length=1200)
    video_discription = models.TextField()
    create_date = models.DateField(default = timezone.now)


    def __str__(self):
        return self.video_title

videos/views.py

class VideosListView(ListView):
    model = VideosList
    context_object_name = 'videos_lists'  
    template_name = "videos/videos_lists.html"

    def get_queryset(self):
        return VideosList.objects.filter(create_date__lte=timezone.now()).order_by('-create_date')





class VideosModelListView(ListView):
    model = VideosModel
    template_name = "videos/list_videos.html"
    context_object_name = 'videos_list'  

    def get_queryset(self,*args, **kwargs):
        videoslist = get_object_or_404(VideosList, list_title=self.kwargs.get('list_title'))
        return VideosModel.objects.filter(videos_lists=videoslist).order_by('-create_date')

videos/urls.py

app_name = 'videos'

urlpatterns = [
    path('list/',views.VideosListView.as_view(),name ='videos_playlist'),
    path('list/<str:list_title>/',views.VideosModelListView.as_view(),name ='list_videos'),
]

videos/videos_list.html

{% extends 'pages/videos.html' %}

In your videos/videos_list.html update <a> tag like this,

<a href="{% url 'videos:list_videos' all_lists.videos_lists.list_title %}"> {{ all_lists.list_title }}</a>
