Chapter 7 - issue with shop.views.product_list returning None

[gwt0083]

After typing http://127.0.0.1:8000, I get this error:
ValueError: The view shop.views.product_list didn't return an HttpResponse object. It returned None instead.

I have verified my files against the example here and don't find any issues, they appear to match. Any suggestions, view matches
this project exactly.

Thank you,

Can you share your code?

I am assuming it is the views file that is the issue, here is a cut and paste of shop-->views.py:

from django.shortcuts import render, get_object_or_404
from .models import Category, Product

def product_list(request, category_slug=None):
category = None
categories = Category.objects.all()
products = Product.objects.filter(available=True)
if category_slug:
category = get_object_or_404(Category, slug=category_slug)
products = products.filter(category=category)
return render(request, 'shop/product/list.html',
{'category': category,
'categories': categories,
'products': products})

def product_detail(request, id, slug):
product = get_object_or_404(Product, id=id, slug=slug, available=True)
return render(request, 'shop/product/detail.html',
{'product': product})
