That config is populated when ActiveStorage::Blob is loaded. You may need to reference ActiveStorage::Blob first in dev to autoload it.

Note:

• This config is undocumented, which means it’s a framework implementation detail, not intended to be used directly.
• The forum is the best place to ask for support.
