TypeError: context must be a dict rather than str

Question

I am newbie. I am currently learning django.
I have a page with a meeting of goods:

URLS.PY

urlpatterns = [

    path("productsHTML/<str:uuid>", productHTML, name = "productHTML"),
    path("productsHTML/", productsHTML, name = "productsHTML")
]

VIEW.PY

def productsHTML(request):
    all_products = {"products": Product.objects.all()}
    return render(request, "products.html",all_products) 

def productHTML(request, uuid):
    product = Product.objects.get(id = uuid)
    
    value = [product.name, product.category, product.marka, product.privod, product.loshad_sila, product.box_peredach, product.volume_dvigatel]
    values = {"values": value}

    return render(request, "product.html", uuid, values)

PRODUCTS.HTML

{% block content %}
<h2>Продукты</h2>
<hr>
    {%if products %}
        {% for product in products %}
                        
            <p><b>Категоия: </b>{{ product.category}}</p>
            <p><b>Название: </b><a href="http://127.0.0.1:8000/productsHTML/{{ product.id }}">{{ product.name}}</a></p>
            <p><b>Цена: Бесплатно</p> 
            <hr> 

        {% endfor %}
            
    {% endif %}
        
{% endblock %}

PRODUCTS.HTML

{% extends 'products.html' %}

{% block title %}Продукт{% endblock %}

{% block content %} 
        {% if values %}
                {% for value in values %}
                    <p><b>Категоия: </b>{{ value.category }}</p>
                    <p><b>Название: </b>{{ value.name }}</p>
                    <p><b>Марка: </b>{{ value.marka }}</p>
                    <p><b>Привод: </b>{{ value.privod }}</p>
                    <p><b>Лошадиные силы: </b>{{ value.loshad_sila }}</p>
                    <p><b>Коробка передач: </b>{{ value.box_peredach }}</p>
                    <p><b>Объём двигателя: </b>{{ value.volume_dvigatel }}</p>
                    <p><b>Цена: Бесплатно</p> 
                
                {% endfor %}

            <button>КУПИТЬ</button>

        {% endif %}     
{% endblock %}

I need to click on the link contained in the product name to be redirected to the product page with the address http://127.0.0.1:8000/productsHTML/ product id.
If needed, I can provide additional information.
Error: TypeError: context must be a dict rather than str.
Thank you in advance!

I’ve been struggling with this for 3 days now. I tried to pass variables to the template in a different way, but to no avail.

return render(request, "product.html", uuid, values)

The problem is that you’re passing uuid as the third argument, but render() expects that the third argument will be a context dictionary.

Why are you even passing uuid to render()? The template does not appear to need it.
