Branden Moore created TINKERPOP-1567:
----------------------------------------
Summary: GraphSON deserialization fails with within('a')
Key: TINKERPOP-1567
URL: https://issues.apache.org/jira/browse/TINKERPOP-1567
Project: TinkerPop
Issue Type: Bug
Components: language-variant, server
Affects Versions: 3.2.3
Environment: Demonstrated on Ubuntu 14.04 and Debian Testing
Reporter: Branden Moore
Priority: Minor
Using the gremlin-python interface, when I attempt to run an example from the
Documentation of {{where}}:
{code}
g.withSideEffect('a','josh','peter']).V(1).out('created').in_('created').values('name').where(P.within('a')).toList()
{code}
The server returns a deserialization error:
{noformat}
{{[WARN] OpExecutorHandler - Could not deserialize the JSON value as required.
