> Getting Lambda  comparator message for .profile() step

>             Project: TinkerPop
>          Issue Type: Bug
>          Components: process
>    Affects Versions: 3.2.6
>            Reporter: Shaunak Das
>            Priority: Minor
>
> Ran into this message when adding a .profile() step, even though Gremlin 
> query does not have any lambda steps:
> {code}
> gremlin> 
> g.V().has("Question","questionType","yes/no").in("has_question").order().by(inE("reviewed").values("rating").mean()).profile()
> The provided step contains a lambda comparator: 
> OrderGlobalStep([[[VertexStep(IN,[reviewed],edge), 
> PropertiesStep([rating],value), MeanGlobalStep@[~gremlin.profile]], incr]])
> Type ':help' or ':h' for help.
> Display stack trace? [yN]
> {code}
