Wagtail & Django issues

Question

I just updated from Wagtail 2.11.2 to 2.15.1 and Django 2.2.6 to 3.0. Everything works locally but when I deploy and visit the cms I get an internal server error.

The error in django_errors.log is:

Internal Server Error: /cms/

We have a deployment pipeline to staging which has run but I've also tried to manually deploy this just to see and they are both the same.

I've also run python3 manage.py collectstatic (also with flags --noinput --clear).

We are using ManifestStaticFilesStorage:

STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'

I'm looking for any suggestions on this. I'm not really a Python dev, I was just asked to do some updates on this system.

Are you able to duplicate this error in your development environment? — Code-Apprentice, Jan 04 '22 at 19:53
No. I haven't seriously tried, I suppose I would just run `collectstatic` locally? — tfantina, Jan 06 '22 at 01:41

I've found that ManifestStaticFilesStorage doesn't always work correctly depending on how the templates are constructed and the static files are referenced. I'd say that your problem is almost certainly being caused by the use of ManifestStaticFilesStorage. Just comment it out, and then restart your server.

If collectstatic doesn't run completely correctly, then ManifestStaticFilesStorage won't have a mapping to every static file, and you'll get a server error with no other helpful information.

I ended up having to upgrade several packages on the server, I'm doubt this answer will ever be relevant to anyone else but the solution in this particular instance was to run the following commands:

sudo apt-get upgrade python-setuptools
pip install --upgrade cryptography
pip install --upgrade pip
pip install setuptools_rust
python3 -m pip install -U pip setuptools

pip3 install --upgrade -r requirements.txt


python3 manage.py migrate

sudo supervisorctl stop all
sudo supervisorctl start all
