> Key: TINKERPOP-2084
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2084
> Project: TinkerPop
> Issue Type: Improvement
> Components: console
> Affects Versions: 3.3.4
> Reporter: stephen mallette
> Assignee: stephen mallette
> Priority: Minor
>
> When sending remote scripts through the Gremlin Console that return an error,
> the console will display the message from the server, but if you view the
> stack trace it displays the local one which isn't helpful in understanding
> the cause of the failure. Here's an example:
> {code}
> gremlin> g.V().outE().out()
> org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerEdge cannot be cast
> to org.apache.tinkerpop.gremlin.structure.Vertex
> Type ':help' or ':h' for help.
> Display stack trace? [yN]y

> This forces the user to then dig around server logs to try to determine the
> more accurate cause of the error to their script. That's not always easy,
> especially if the console is connected to a Remote Gremlin Provider and
> server access is not possible. This change should only be for actual
> {{ResponseException}} that actually have a stacktrace included, otherwise it
> should just use the local one.
