Django view is rendering 404 page instead of given html template

I'm working on a wiki project with django. I'm trying to render 'add.html' with the view add, but it sends me to 404 instead. All the other views are working fine. How should I fix add?

views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect, HttpResponse
from django.urls import reverse
from django import forms
import re
from . import util


def index(request):
    return render(request, "encyclopedia/index.html", {
        "entries": util.list_entries()
    })

def detail(request, entry):
        #if search based on title returns result
    if util.get_entry(entry):
        content = util.get_entry(entry)
        return render(request, "encyclopedia/details.html",
                      {
                          "title": entry,
                          "content": content
                      })
    else:
        return render(request, "encyclopedia/404.html", {
              'entry': entry
        })

def add(request):
    return render(request, "encyclopedia/add.html")




  urls.py:
from django.urls import path

from . import views

app_name = "wiki"
urlpatterns = [
    path("", views.index, name="index"),
    path("<str:entry>/", views.detail, name="entry"),
    path("add/", views.add, name="add"),
]

urlpatterns = [
    path("", views.index, name="index"),
    path("add/", views.add, name="add"),  # place "add/" before "<str:entry>/"
    path("<str:entry>/", views.detail, name="entry"),
]
