Description

I use [True] value as a argument of valueMap() step. And it result in error as below.
(This error didn't occur in Groovy Query and return list of Value Map with id and label)

// Python
graph = Graph()
g = graph.traversal().withRemote(DriverRemoteConnection('ws://localhost:8182/gremlin','g'))

g.V().valueMap(True).toList()
=>
TypeError
----> 1 g.V().valueMap(True).toList()
...
~\site-packages\gremlin_python\structure\io\graphsonV3d0.py in objectify(cls, l, reader)
453 x = 0
454 while x < len(l):
--> 455 new_dict[reader.toObject(l[x])] = reader.toObject(l[x + 1])
456 x = x + 2
457 return new_dict
TypeError: unhashable type: 'dict'
