Error when using Unicorn.call() on a page to call backend method on component.

Hi, can you give me more some more information about this error? Best way would be to fork this repo and replicate it using https://github.com/adamghill/django-unicorn/blob/master/example/www/templates/www/index.html#L8 and https://github.com/adamghill/django-unicorn/blob/master/example/unicorn/components/hello_world.py#L11 or a unit test that demonstrates the issue. Second best would be a small piece of code in this discussion that replicates the problem.

Thanks!

Thank you for your answer, I'm going to explain. I have two components on the same page 'filter' and 'articles' and a menu in my filter components listing different categories. I want that when user click on a specific categorie articles in 'articles' component get updated.

In filter component :

{% for categorie in categories %}
                    <li>
                        <a u:click="Unicorn.call('articles','filter',{{ categorie.id }})" href="#">
                            {{categorie.title}}<span class="category-counter"> ({{categorie.num_articles}})</span>
                        </a>
                    </li>
{% endfor %}

In articles:

class ArticlesView(UnicornView):
    def filter(self, id):
        self.articles = Article.objects.filter(categorie_id=id)

template:

{% extends 'layout.html' %}
{% load static %}
{% load tedy_extras %}
{% load unicorn %}
{% block title %}
       filter 
{% endblock %}

{% block layout %}
    <div class="main-container section-padding">
    <div class="container">
        <div class="row mt-5">
            {% unicorn 'filter' %}
            {% unicorn 'articles' %}
        </div>
    </div>
</div>
{% endblock %}
