Description

g.V(491552912).repeat(__.out("job")).emit().has("staff", Text.textContains('chrism"))
.sideEffect(Lambda.consumer("it") );

is having exception returned as:

org.apache.tinkerpop.gremlin.driver.exception.ResponseException:
javax.script.ScriptException: groovy.lang.MissingMethodException:
No signature of method: static org.apache.tinkerpop.gremlin.process.traversal
**.P.textContains()** is applicable for argument types: (String) values: [chrism]"

- Version: JanusGraph 0.4
- Storage Backend: Cassandra
- Mixed Index Backend: not usd
- Mailing list Thread URL:
- Steps to Reproduce:

# This part of the query works well:
g.V(491552912).repeat(__.out("job")).emit().has("staff", Text.textContains('chrism'))

# This lambda code is also working well, and doing the job on the server, with my closure inside,
g.V(491552912).repeat(__.out("job")).emit().sideEffect(Lambda.consumer("it is having any code here") );

Research direction

Start with the remote-driver execution path for the reproduced traversal combining Text.textContains and Lambda.consumer, using the JanusGraph 0.4 and Cassandra details in the issue. Verify the two working standalone traversals and then determine why their combination raises the reported ScriptException; done means the combined traversal executes without that exception.
