Issue with Django 3.2 and Django-storage 1.14.2 after Upgrading from Django 2.2.28

[Akash Ilangovan]

• Upgraded from Django 2.2.28 to 3.2.
• Using Django-storage 1.14.2.
• Replaced CachedFilesMixin with ManifestStaticFilesStorage.
• Post-upgrade, everything was the same; no other settings changed.
• Issue: self.location is caching a None value that doesn't alter.
• Temporary Fix: Deleting the cache in the debugger manually with a del statement resolves the issue.

Code Snippet:

class StaticFilesStorage(ManifestStaticFilesStorage, S3Boto3Storage):
  def __init__(self, *args, **kwargs):
      S3Boto3Storage.__init__(self, bucket_name=settings.STATIC_FILES_BUCKET, custom_domain=domain(settings.STATIC_URL), *args, **kwargs)
      ManifestStaticFilesStorage.__init__(self, *args, **kwargs)
