When I open the SQL Panel on Django 4.2, django-debug-toolbar 4.1, I get the following warning:
django.utils.deprecation.RemovedInDjango50Warning: The "default.html" templates for forms and formsets will be removed. These were proxies to the equivalent "table.html" templates, but the new "div.html" templates will be the default from Django 5.0. Transitional renderers are provided to allow you to opt-in to the new output style now. See https://docs.djangoproject.com/en/4.2/releases/4.1/ for more details
I tried to narrow down a bit what's causing it using pdb, but I only managed to see that the self is SignedDataForm, not much more.
