Python 3.12 filter bug with Django 4.2.11

[Tim Richardson]

I have a template with a fragment like this:

<span

class="fs-6">Supplier: {{ po_metadata|get_item:dict_item.PONumber|get_item:"supplier" }} PO Date: {{ po_metadata|get_item:dict_item.PONumber|get_item:"order_date" | slice:":10" }} </span>

When using python 3.13.2, I get an exception in django/template/defaultfilters.py slice_filter()

This code does not throw an exception with 3.11

The exception is a Key Error and it happens because instead a list being passed to the filter, a dictionary is. An empty dict in my case.

In python 3.11, the breakpoints in slice_filter() are not hit. Somehow the preceeding filters are behaving differently in case of po_metadata being an empty dict.
