I got the same error while writing code.

enter image description here

started making this project using a video tutorial on YouTube
I think the problem is in the Url files, but I can’t find this problem myself.

Essentially the problem is that when I go to the site and press a certain button, this error appears and does not find this page, why?

my urls.py there may be a mistake here, but that’s for sure

from django.urls import path
from . import views



urlpatterns = [


    path('login/', views.loginPage, name="login"),
    path('logout/', views.logoutUser, name="logout"),
    path('register/', views.registerPage, name="register"),


    path('', views.home, name='home'),
    path('room/<str:pk>/', views.room, name="room"),
    path('profile/<str:pk>',views.userProfile,name="user-profile"),


    path('create-room/', views.createRoom, name="create-room"),
    path('update-room/<str:pk>/', views.updateRoom, name="update-room"),
    path('delete-room/<str:pk>/', views.deleteRoom, name="delete-room"),
    path('delete-message/<str:pk>/', views.deleteMessage, name="delete-message"),

]

if this information is not enough to solve this error, then I can provide my other files with code
