MultiValueDictKeyError - Django

Question

I am having a problem by getting MultiValueDictKeyError in Django. I am trying to logout user from my website so I made the following codes.

In html

    </li>
            <li class="nav-item mr-3">
              <a href="javascript:{document.getElementById('logout').submit()}" class="nav-link">
              <i class="fas.fa-sign-out-alt"></i>Logout 
              </a>
              <form action="{% url 'logout'%}" method="POST" id="logout">
                {% csrf_token %}
                <input type="hidden">
              </form>
            </li>

Here's my login and logout function in say 'accounts/views.py'

    def login(request):
    # request method
    if request.method == 'POST':
        #Saving the username and password in a variable
        username = request.POST['username']
        password = request.POST['password']

        #checking if the user name and password matches using auth function
        user = auth.authenticate(username=username, password=password)

        # checking if the user is found in Database with user name and password, if found then login
        if user is not None:
            auth.login(request, user)
            messages.success(request, "Welcome to BTRE.")
            return redirect('dashboard')
        # if user name and password do not match with DB. display message and redirect to login page.
        else:
            messages.error(request, "Incorect Username and/or Password. Please type correct user name and password")
            return redirect('login')
    else:
        return render (request, 'accounts/login.html')

def logout(request):
    if request.method == 'POST':
        auth.logout(request)
        messages.success(request,"You are now logged out")
        return redirect('index')

from django.urls import path
from . import views

urlpatterns = [
    path('login', views.login, name ='login'),
    path('logout', views.login, name ='logout'),
    path('register', views.register, name ='register'),
    path('dashboard', views.dashboard , name = 'dashboard')
]

sorry guys for wasting your time. one little error in urls.py causes me a headache for three hours. I appreciate your time guys. Again apologize for wasting your time.
