In this statement I wrote, "values" and "keys" are attribute names used for
sorting. In this context, they are extracted from the previous results,
specifically corresponding to the key and value used in the
.groupCount().by("tag.name")
step, rather than referring to specific properties in the schema statement.
A similar query that also use `.order().by(values, desc).by(keys, asc)` can
work successfully.
```
result =
g.V().has("Person","id",$personId).repeat(both("Person_knows_Person"))
.emit().times(2)
.dedup().has("id", neq($personId))
.as("friends")
.in("Post_hasCreator_Person")
.where(
__.out("Post_hasTag_Tag").has("name",$tagName)
)
.as("Post")
.out("Post_hasTag_Tag")
.has("name", neq($tagName))
.as('Tag')
.project("postId","tagName")
.by(select("Post").values("id"))
.by(select("Tag").values("name"))
.dedup()
.groupCount().by(select("tagName"))
.unfold()
.order().by(values, desc).by(keys, asc)
.limit(10)
.project("otherTag.name","postCount")
.by(select(keys))
.by(select(values))
result
```
So，I think is not that problem,thank u
