The created swagger schema definition is not valid (schema check error). This affects all API versions. The violating section is the following

inventory:
   properties:
    nodes:
      type: array
     items:
       $ref: "#/definitions/"

The "#/definitions/" is not complete.

The swagger schema can be located in the released schema /org/onap/aai/aai-common/aai-schema/1.2.1-SNAPSHOT/aai-schema-1.2.1-20180316.183213-16.jar
