In testing out under development json-schema 2020-12 support, there's a few issues with 'unevaluatedProperties' and the graph schema. If 'graph.yaml#/properties/port' is used, then neither the port nor the endpoint(s) can have additional properties. 'graph.yaml#/$defs/port-base' needs to be used instead.
