Field sender in com.example.service.OrderService required a bean of type
'com.example.notification.NotificationSender' that could not be found.

The following candidates were found but could not be injected:
  - Bean method 'sesNotificationSender' in 'NotificationConfig' not loaded because @Profile [prod] did not match active profiles [dev]

Action:
Consider defining a bean of type 'com.example.notification.NotificationSender' for the active profiles.
