Hi,
The trick to Gremlin is to know that an expression is an Iterator and thus,
must be iterated.
n.outE.inV.inE.outV.groupCount(m);m.sort{a,b -> b.value <=> a.value}
Should be:
n.outE.inV.inE.outV.groupCount(m);m.sort{a,b -> b.value <=> a.value} >>
-1
>> -1 is equivalent to while(itty.hasNext()) { itty.next() }
When you do sutff in the Gremlin terminal, the terminal will say: "oh, you
returned an iterator, let me iterate through the results for you."
See the first point in:

Question: where are you setting the variable 'n' ? Is that Gremlin plugin thing?
Hope that helps,
Marko.
