> I am using gremlin to write some graph query test(see below for detailed
> code) which run on Tinkerpop(3.3.3), but I got the following errors:
> g.V().hasLabel('person').has('Person.id',
> 609).store('p').both('knows').group().by().by(both('knows').both('knows').where(within('p')).count())
> {quote}Java.lang.Long cannot be cast to
> org.apache.tinkerpop.gremlin.process.traversal.traverser.util.TraverserSet
> {quote}
> But the following two queries work well.
> # {{g.V().hasLabel('person').has('Person.id',
> 609).store('p').both('knows').group().by(both('knows').both('knows').where(within('p')).count())}}
> # g.V().hasLabel('person').has('Person.id',
> 609).store('p').both('knows').group().by().by(both('knows').where(within('p')).count())
> I don't have any idea about this, any solution will be appreciated. Thank in
> advance.
