Bug #80207 for REST-Neo4p: die after get_index_by_name

I'd like to write something like this: > my $idx = > REST::Neo4p->get_index_by_name('my_index','node');if ( > INDEX_NOT_FOUND_CONDITION) { REST::Neo4p::Index->new('node', > 'my_index'); } The > same issue also concerns other methods ( get_node_by_id, > get_relationship_by_id, etc.... ) Thanks.
