Just ran the test suite of a project on Django 4.0a1 (with Python 3.8) and
ran into the following issue:
We have a fairly simple `FormView` that defines the following
`form_invalid` method:
{{{
def form_invalid(self, form):
return JsonResponse(form.errors, status=400)
}}}
This worked fine before, but with Django 4 this raises the following
error:
`TypeError: In order to allow non-dict objects to be serialized set the
safe parameter to False.`
Wrapping `form.errors` with `dict()` fixes this, but I'm not sure this
should be necessary.
