Ranger Trino plugin - NullPointerException at RangerTagEnricher

Question

I have build the Ranger Trino plugin from latest released 2.4.0 Source code Ranger. I have Apache Atlas as tag provider for ranger for tag based policies. I am facing below exception while executing any query from trino when I enable the plugin.

java.lang.NullPointerException: Cannot invoke "java.util.Collection.size()" because "ret" is null
