Description
We are currently using OrientDB as graph database backend. OrientDB allows properties with null values. The orientdb database is requested with Groovy/Gremlin request.
When we are requesting for a 'subgraph' step (which use the tinkergraph on memory database for creating the subgraph), an exception is thrown when the vertex of Orientdb contains properties with null values:
Part of the exception trace:
