Hi,
It seems that in at least the latest version of Jazzmin, the .map files are once again missing from the vendor/ folder.
We got the same error that has been discussed in a previous issue (#488):
$ python3 manage.py collectstatic --noinput
Post-processing 'vendor/bootswatch/cerulean/bootstrap.min.css' failed!
[...]
ValueError: The file 'vendor/bootswatch/cerulean/bootstrap.min.css.map' could not be found with
<django.contrib.staticfiles.storage.ManifestStaticFilesStorage object>.
Could you please include them on the vendor folder, so we can run collectstatic without bumping into this error?
