Sample error message: application-group -> Internet_Access 'quickoffice-pro' is not a valid reference
Note: quickoffice-pro is an application in Palo Alto Networks Application Database and Internet_Access is application group.
When trying to push the config from panorama to the firewall, this error is seen. This occurs when the Application and Threats database on the firewall is not up to date.
In this case "quickoffice-pro" would be included in Panorama's content and not on the device's content.
Update the Application and Threats Database on the Firewall to match the version on Panorama
