How to reproduce:
In apps.py, put the following code, and update __init__.py or the settings
to have this app config be used.
{{{
from django.apps import AppConfig
class MyException(Exception):
def __init__(self, value: str, other_thing: str):
super().__init__(value)
self.ot = other_thing
class Config(AppConfig):
name = "myapp"
verbose_name = "My App"
def ready(self):
raise MyException("foo", "bar")
}}}
The problem is that `django.utils.autoreload.raise_last_exception` tries
to construct a new exception of the same type, with 1 argument (the
original exception). Note that this behavior was changed in
c8720e7696ca41f3262d5369365cc1bd72a216ca, it used to just re-raise the
exception value. I don't know why it was changed.
I noticed this issue as a result of https://gitlab.com/alantrick/django-
