----------------------------------------
Component/s: io
> Subgraph with graphson v3 causes serialization error
> ----------------------------------------------------
>
> Key: TINKERPOP-3154
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3154
> Project: TinkerPop
> Issue Type: Bug
> Components: io
> Affects Versions: 3.7.3
> Reporter: Andrea C
> Priority: Major
>
> Usage of subgraph step with graphson v3 results in serialization error.
> Can be reproduced by adding this unit test to the
> `HttpDriverIntegrateTest.java`:
> {code:java}
> @Test
> public void shouldSubmitScriptWithGraphSONWithSubgraph() throws Exception {
> final Cluster cluster = TestClientFactory.build()
> .channelizer(Channelizer.HttpChannelizer.class)
> .serializer(Serializers.GRAPHSON_V3)
> .create();
> try {
> final Client client = cluster.connect();
>
> client.submit("g.E().hasLabel('knows').subgraph('sg').cap('sg')").all().get();
> } catch (Exception ex) {
> throw ex;
> } finally {
> cluster.close();
> }
> }{code}
> {code:java}
