>
> Key: TINKERPOP-2312
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2312
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.5.0
> Reporter: Stephen Mallette
> Priority: Major
>
> With TINKERPOP-2235 in place, {{null}} becomes valid to the language which
> means that we could fix:
> {code}
> gremlin> g.V().group().by('age')
> The property does not exist as the key has no associated value for the
> provided element: v[3]:age
> Type ':help' or ':h' for help.
> Display stack trace? [yN]n
> {code}
> so that users dont' need to do added filtering magic to deal with those kinds
> of exceptions.
