Dublin AAI Molde Loader fails to ingest SDC service models

Vivekanandan Muthukrishnan
 

HI AAI Team,

We are seeing SDC service distribution error, and for some reason AAI model loader is not able to ingest the SDC service models.

In the AAI Resources logs, we see that ModelLoader:Extension class not found: org.onap.aai.extensions.v16.serviceDesignAndCreation.ModelExtension message. 

Did anyone face this issue? Are there any workaround to resolve this one. Please refer the below log snippet for more information.
