Hi! Do you have a full traceback? Or is this coming from the rust extension?

[LilyFoote]

Can you confirm that the test passes without kolo?

[LilyFoote]

Actually, it looks like this might be your problem: https://stackoverflow.com/a/52490842

[vaibhavnagda]

Can you confirm that the test passes without kolo?

Yes, tests run fine without kolo

[LilyFoote]

Can you share a working example, including your views, urls and test code?

[we684123]

also have this problem ( ╯□╰ ) python package kolo v2.11.0 is ok, but update to v2.12.0 can't trace , then degrade to v2.11.0 is work again

VScode kolo version : v2.7.0

[LilyFoote]

@we684123 Today I released 2.12.3 - can you let me know if you still see this with that version?

[we684123]

@LilyFoote thank you update v2.12.3 , but is not fixed 〒▽〒

---

here is a minimal realization for reproduce

poetry init 

poetry add django

poetry add kolo@2.11.0 --group dev

poetry shell

django-admin startproject for_kolo_debug

( Move creation to previous folder )

add 'kolo.middleware.KoloMiddleware' to setting MIDDLEWARE link：

MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
    'kolo.middleware.KoloMiddleware',
]

python manage.py migrate

python manage.py runserver 127.0.0.1:8002

( open http://127.0.0.1:8002/ web) ( can trace ) ( 'ctrl + C' to close python )

p add kolo@2.12.3 --group dev

python manage.py runserver 127.0.0.1:8002

( open http://127.0.0.1:8002/ web ) ( can't trace )

[LilyFoote]

@we684123 Thanks! I think I've fully fixed it this time around with 2.12.4.

[we684123]

@LilyFoote Thank you~ very much~ now is working kolo v2.9.0 (VScode) kolo v2.12.4 (Python)

[LilyFoote]

@vaibhavnagda Let me know if you still see this failure.
