Description

 

We are trying to read metadata for https://services.odata.org/V4/(S(qumvkqavql1jwrawmicd45j1))/TripPinServiceRW/$metadata

using below snippet of code. 

 

ODataClient client = ODataClientFactory.getClient();
this.edm = client.getReader().readMetadata(metadataStream);

As you can see above service has a 'Singleton" named "me".   When we try to retrieve the singletons from EntityContainer we get nothing(as shown below).

edm.getSchemas().stream()
 .map(EdmSchema::getEntityContainer)
 .filter(Objects::nonNull).map(EdmEntityContainer::getSingletons)
.flatMap(Collection::stream)
.collect(Collectors.toList());
