Página não encontrada (404) Método de solicitação: URL de solicitação GET: http://127.0.0.1:8000/

Eu estava acompanhando a documentação do django e criando um aplicativo de pesquisa simples. Me deparei com o seguinte erro:

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
    ^polls/
    ^admin/
The current URL, , didn't match any of these."
