Answer 1

According to the error stack trace, Service artifact you are going to publish as API doesn't contain service endpoints. Service Endpoint is a must attribute to create an API definition at the APIStore.
Please check whether you have mentioned endpoint details in Service metadata.
It will be great if you can include the G-Reg + APIM versions you are using.
