Django Version: 1.9.12

Exception Value:
Required parameter name not set

Since I change where my medias and statics file have to be store (meaning now it's in a AWS S3) I can't upload images anymore through the django-filer plugin.
I thought first it was coming from their plugin but the stack trace point to boto3.
I'm using:
django==1.9.12 && django-storages==1.5.2.

Before posting the report, a collectstatic copies without problems my files to s3. Meaning that it seems to be properly configured, with the classical:
`AWS_STORAGE_BUCKET_NAME = os.environ.get('DJANGO_AWS_STORAGE_BUCKET_NAME')
AWS_ACCESS_KEY_ID = os.environ.get('DJANGO_AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.environ.get('DJANGO_AWS_SECRET_ACCESS_KEY')

AWS_S3_CUSTOM_DOMAIN = os.environ.get('DJANGO_AWS_STORAGE_BUCKET_NAME', 'bucketname.s3.amazonaws.com')

STATICFILES_LOCATION = 'static'
STATICFILES_STORAGE = 'project.storage.StaticStorage'
STATIC_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, STATICFILES_LOCATION)

MEDIAFILES_LOCATION = 'media'
MEDIA_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, MEDIAFILES_LOCATION)
DEFAULT_FILE_STORAGE = 'project.storage.MediaStorage' `

Do you have any clue about what the problem could be? I'm completely hopeless about solving it.

Here the stack trace:

The only way I can reproduce this is to pass None into connection.Bucket, I don't think that this library is the issue.

So I had a similar problem when I was trying to run collectstatic in my local environment. The code was looking for AWS_STORAGE_BUCKET_NAME to be set ('name' variable) in my environment variables, which it was not in my local environment. But I was supposedly in a DEBUG mode with my debug/local environment variables set, so it should have never been getting to this code in the first place!

It turned out that my local environment and the env variables were just messed up, and I had sort of a half-debug env and a half-prod env on my local. So maybe make sure you definitely have the environment variables set correctly for the environment you think you are using so it doesn't get into a weird state where it is looking for AWS variables that aren't set because you mean for them not to be. Hope this helps someone.
