[FIXED] Getting DEFAULT_FILE_STORAGE/STORAGES are mutually exclusive when upgraded to 4.2

Issue

We are in process to upgrade to django 4.2. However we are facing above issue in running django peroject. We have already setup new way of STORAGES in settings.py i.e.

STORAGES = {
            "staticfiles": {"BACKEND": "custom.core.storage.GzipManifestStaticfilesStorage"},
            "default": {"BACKEND": "django.core.files.storage.FileSystemStorage"},
        }

But its not working and getting said error in running project. But, when we manually go and remove DEFAULT_FILE_STORAGE from django\conf\global_settings.py file then at least it doesn't give above issue. Any suggestion(s) how to fix it, thanks!

Solution

Finally it's fixed. I had a silly mistake that i was still using django-configurations version 2.3.1 but once I moved to django-configurations version 2.5. Then issue is gone.
