--------------------------------------------- > > Key: TINKERPOP-1898 > URL: https://issues.apache.org/jira/browse/TINKERPOP-1898 > Project: TinkerPop > Issue Type: Bug > Components: python, server > Affects Versions: 3.3.1 > Reporter: Jean-Philippe Braun > Assignee: stephen mallette > Priority: Major > Fix For: 3.2.8, 3.3.2 > > Attachments: bug.py > > > I'm trying to use bindings in a traversal strategy like: > {code:java} > graph = Graph() > g = > graph.traversal().withRemote(DriverRemoteConnection('ws://localhost:8182/gremlin', > 'g')) > g = g.withStrategies( > SubgraphStrategy(vertices=__.has('foo', ('b', 5))) > ){code} > This works unless there is a use of lambda in the traversal: > {code:java} > g.V().toList() # will work > g.V().filter(lambda: "true").toList() # this will not{code} > Here is the full TB on the server: > {code:java} > [ERROR] TraversalOpProcessor - Could not deserialize the Traversal > instance >
