DisallowedModelAdminLookup at /admin/store/product/

I encountered this error at Django lecture pt 1 8- Providing Links to Other Pages (5:16)
where in the django admin, you can click products count in the collection page to go to the collection with products.

Here are my code-along code in the admin.py and I don’t see the difference from Mosh’s. Thank you in advance.
class CollectionAdmin(admin.ModelAdmin):
list_display = [‘title’, ‘products_count’]

def products_count(self, collection):
    url = (
        + '?'
        + urlencode({
            'collection__id': str(collection.id)
    return format_html('<a href="{}">{}</a>',url, collection.products_count)
def get_queryset(self, request: HttpRequest) -> QuerySet[Any]:
    return super().get_queryset(request).annotate(
        products_count = Count('product')

Ok…after trying…got the solution
class ProductAdmin(admin.ModelAdmin):

# need to add this line inside class ProductAdmin
list_filter = [‘collection’]
