We aren't entirely sure where the issue lies, once it becomes clearer I'll change the title.

The discussion around this issue can be found here : https://pony-poc.apache.org/thread.html/4402fe28badece112e51cf7d369844f8da3f382d3ce1ffb7666ed0bf@1446656912@%3Cdev.tinkerpop.apache.org%3E

In essence, when queries against gremlin-server are made using authentication in-session a couple of weird behaviors can be noticed:
- Variables need to be properly defined via {{def v = ...}} or we will get an exception.
- Variables set within queries aren't available in the following queries

Bellow is an example of payloads that recreate this error:
{code}
Message :

Response: 
{'status': {'message': "startup failed:\nScript2.groovy: 1: [Static type checking] - The variable [v] is undeclared.\n @ line 1, column 1.\n v=graph.addVertex('name', 'Dave')\n ^\n\n1 error\n", 'code': 597, 'attributes': {}}, 'requestId': '1afa7873-df64-43a1-82a2-4aaa3cc35d82', 'result': {'meta': {}, 'data': None}}
{code}

It's worth noting that this same scenario seems to work when using gremlin-driver as per these tests : https://github.com/apache/incubator-tinkerpop/commit/4cb087d039990f643494146e48ab95264cc99805

First step will probably be to reproduce this with the "simple" client.
