Few functions not working in Gremlin

[Siva Punnaivanam]

Hi Team, 

I have started TinkerPop console and using the modern graph I am able to test the functions like .map, .transform, .contains and .matches etc. 

Please note that, I have created the modern graph in tinkerpop console using below commands.

graph = TinkerFactory.createModern()

g = graph.traversal()

But I have a Gremlin  database created in Azure environment. If I connect to that database through tinkerpop console, above functions are not working. 

I am getting below error message. What could be the issue?

gremlin> g.V('8cc7ca46-53a7-4a57-a401-37aaec871afe').values('createdDate').map{new Date(it.get()).format('yyyy-MM-dd')}

ActivityId : a9c72210-c159-476e-bd28-c8b10eb5396d

ExceptionType : GraphSyntaxException

ExceptionMessage :

        Gremlin Query Syntax Error: Script compile error: Unsupported groovy language rule: 'closure' text: '{newDate(it.get()).format('yyyy-MM-dd')}' @ line 1, column 70.

I assume you're talking about CosmosDB when you say a "Gremlin Database created in an Azure environment"? if so, CosmosDB does not support lambdas so your call to map{} won't work. Also note that CosmosDB does not yet support all Gremlin steps just yet:
