When creating a service instance in VID (SB-07), SO returns the following (as shows in VID console):

"requestId": "52ec7fa6-f137-4794-843d-b036c77d8f37",
"requestType": "createInstance",
"timestamp": undefined,
"requestState": "FAILED",
"requestStatus": "Exception in createProject. org.openecomp.mso.client.aai.exceptions.AAIUriNotFoundException: Service instance 4d19184a-1528-4ff0-8ca5-2799c2683b8a not found at: /nodes/service-instances/service-instance/4d19184a-1528-4ff0-8ca5-2799c2683b8a",
"percent-progress": "100"

"requestId": "52ec7fa6-f137-4794-843d-b036c77d8f37"
}
}

The service instance gets created though, and written to AAI (found it using VID search by instance ID of: 4d19184a-1528-4ff0-8ca5-2799c2683b8a) but a success message is expected .
