Разобрался с этой штукой. Это проблема ActiveStorage - когда они перешли с active-storage на active-storage-blob, они никогда не перенесли это изменение обратно в Rails 5.2. Или, по крайней мере, пока не
Для тех, кто все еще имеет эту проблему, до тех пор, пока она не будет перенесена, любой может исправить ее: добавьте два пустых файла: lib/azure/storage/core/auth/shared_access_signature.rb и lib/azure/storage.rb
Добавьте это в config / initializers / active_storage_6_patch.rb (это текущая основная версия модуля ActiveStorage):
require "azure/storage/blob"
require 'active_storage/service/azure_storage_service'
module ActiveStorage
# Wraps the Microsoft Azure Storage Blob Service as an Active Storage service.
# See ActiveStorage::Service for the generic API documentation that applies to all services.
