}}}
**Steps to reproduce the issue**
Install the following packages
{{{
Django==4.1
djangorestframework~=3.13
}}}
Start a new project
{{{
django-admin startproject mysite
}}}
Add `rest_framework` to installed apps
Update `settings.py` to use `ManifestStaticFilesStorage`
{{{
STATIC_ROOT = BASE_DIR / 'static'
STATICFILES_STORAGE =
'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'
}}}
Run `collecstatic`
It was working fine with 4.0, so my assumption is that it is related to
the newly added "Support for finding paths in CSS source map comments".
At first sight, it seems it expects the *.map file to exist, which may not
be the case, especially for packages outside of my control.
