Passing empty parameter on neighbors() fails query install

When I try running the below code snippet I receive an error message saying “Failed to add query to GSQL.” on release_3.3.0_11-01-2021.

ACCUM s.@neighbor += tgt.neighbors()

Looking in the error log, there is a message about null pointer exception: ( java.lang.NullPointerException

However if I pass a parameter to the neighbors method, the query installs just fine.
ACCUM s.@neighbor += tgt.neighbors(“hasAccount”)

It would be nice to get the no parameter neighbors() function to work again.
