----------------------------------------
Issue Type: Bug (was: Improvement)
> Issue with bindings in strategies and lambdas
> ---------------------------------------------
>
> 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
> 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
