RecursionError: maximum recursion depth exceeded while getting the str of an object

[Chuox]

I have this on my .py file component

from django_unicorn.components import UnicornView
import requests
from bs4 import BeautifulSoup

class ContcompView(UnicornView):
    url = "https://example.com"
    headers = {
    'Access-Control-Allow-Origin': '*',
    'Access-Control-Allow-Methods': 'GET',
    'Access-Control-Allow-Headers': 'Content-Type',
    'Access-Control-Max-Age': '3600',
    'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0'
    }
    cuenta = dict()
    palabras = []

    def count(self,*args,**kwargs):
        self.page = requests.get(self.url)
        self.data = self.page.text
        self.soup = BeautifulSoup(self.data,features="html.parser")
        self.text = self.soup.get_text()
        self.palabras = self.text.split()
        self.auxpalabras = []
        for palabra in self.palabras:
            if palabra in self.cuenta:
                self.cuenta[palabra] += 1
            else:
                self.cuenta[palabra] = 1
                self.auxpalabras.append(palabra)
        self.palabras = self.auxpalabras

And this on my .htm file component

<div>
    <form unicorn:submit.prevent="add">
        <input class="textinput textInput form-control" type="text" unicorn:model.lazy="url" placeholder="url" id="url"></input>
    </form>
    <button class="btn btn-outline-info" unicorn:click="count">Contar Palabras</button>
<!-- TODO: Check box si se desea incluir articulos -->
<!-- TODO: Mostar pagina de espera mientras se realiza el scraping -->
    <p> 
        {% if palabras %}
        <ul>
            {% for key, val in cuenta.items %}
                <li>{{key}}: {{val}}</li>
            {% endfor %}
        </ul>
        <button class="btn btn-outline-info" unicorn:click="$reset">Limpiar</button>
        {% else %}
            Agregue una dirección url y haga click en el boton para contar las palabras en la pagina web, el proceso es algo lento, dependiendo del contenido de la pagina.
        {% endif %}
    </p>
</div>

If I run the code and the url get small text as https://example.com it runs ok, but when I run something with much text as https://es.wikipedia.org/wiki/Castell%C3%B3n_de_la_Plana I get the "RecursionError: maximum recursion depth exceeded while getting the str of an object"

Does anyone has a workaround for this?
