error creating a vertex

[binarymatt]

i'm following the guide in the docs and i am getting the following error when I try to create my first vertex, james = g.vertices.create(name="James").

({'status': '400', 'access-control-allow-origin': '*', 'content-type': 'application/json; charset=UTF-8', 'content-length': '1113', 'server': 'Jetty(9.0.5.v20130815)'}, '{\n  "message" : "javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: groovy.lang.MissingMethodException.setMaxBufferSize() is applicable for argument types: () values: []",\n  "exception" : "BadInputException",\n  "fullname" : "org.neo4j.server.rest.repr.BadInputException",\n  "stacktrace" : [ "org.neo4j.server.plugin.gremlin.GremlinPlugin.executeScript(GremlinPlugin.java:88)", "java.lang.reflect.Method.invoke(Method.java:606)", "org.neo4j.server.plugins.PluginMethod.invoke(PluginMethod.java:61)", "org.neo4j.server.plugins.PluginManager.invoke(PluginManager.java:168)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:312)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:134)", "java.lang.reflect.Method.invoke(Method.java:606)", "org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:132)", "org.neo4j.server.rest.security.SecurityFilter.doFilter(SecurityFilter.java:112)", "java.lang.Thread.run(Thread.java:744)" ]\n}')

Any idea what I might be doing wrong? I'm using neo4j and have followed the user guide.

Hi - What version of Neo4j Server are you running?

[binarymatt]

Neo4j Community Edition 2.0.0

[espeed]

Hi -

The Neo4j 2 Blueprints/Gremlin implementation was just merged a few days ago into Blueprints 2.5-SNAPSHOT, and there are still some issues to iron out.

See https://groups.google.com/d/topic/gremlin-users/ICiWgw_wAJE/discussion

If you're down to experiment, make sure you're using the latest Blueprints/Gremlin and let us know how it goes.

Or if you want something more stable, use Neo4j 1.9x until the 2.0 updates are fully tested.

Hi, I am using neo4j-server-2.0.1 and today version of gremlin-plugin and I get same error.

Any chance to solve this issue?

[FrostyX]

With neo4j-server-1.9.6 code gives no error.

[espeed]

@FrostyX Are you using the Gremlin Plugin from GitHub master: https://github.com/neo4j-contrib/gremlin-plugin ?

[FrostyX]

Yes, and I have up to date version.

[atomos]

Same issue for me with neo4j-community-2.0.1 and the latest gremlin-plugin on github.

[JobJob]

Yeah I have the exact same issue on OSX 10.7.5 with Gremlin Plugin from GitHub master: https://github.com/neo4j-contrib/gremlin-plugin Anyone managed to get bulbs working with neo4j 2.0?

[espeed]

Hi All - I've been slammed so I haven't had time to fix this, but if anyone wants to, it should just be a matter of updating the neo4jserver/gremlin.groovy to Blueprints/Gremlin 2.5 -- the rexster/gremlin.groovy has already been updated for gremlin 2.5 so you can reference it for hints. I'll be in and out all day, but ping me if you have any questions.

[JobJob]

Hi submitted a pull request, I just replaced neo4jserver/gremlin.groovy with the one in rexster/gremlin.groovy (in my site packages) and it seems to work, haven't tested it much though. Cheers James!

[arusahni]

I'm still getting this error. Was the pull request merged in?

[JobJob]

Um don't remember, but maybe not. The fix is easy as I described though.

@JobJob can you point me into the direction of your pull request, so I can do this in my own repo? I'm also getting this error, and I can't move on as it is...

[dbunskoek]

Nevermind, I found it :)

How is anyone supposed to actually get started using Bulbs if it doesn't work out of box for the latest versions of both Gremlin-Plugin/Gremlin and Neo4J?

[JobJob]

Yeah it's a shame I personally haven't been using it, but fix (for 9 months ago's version) is above.

[s7ephen]

@JobJob so what was the fix!? To cp -r rexster/gremlin.groovy to $NEO4JWORKINGDIR/ ? What if you aren't using rexster?

[JobJob]

Yep, from memory that just puts a newer version of gremlin.groovy which is more compatible with bulbs/whatever the problem was :) apologies I've forgotten, did you try it, did it work?

[JobJob]

paraphrasing myself above: in my site packages/bulbs I just cp rexster/gremlin.groovy neo4jserver/ i.e. replacing the one in the neo4jserver folder with the one from rexster/gremlin.groovy which is more up to date apartment, and it seemed to work, haven't tested it much.
