I have many authors (as nodes) authoring multiple Work of Arts (wokas), also as nodes. I want to fetch the authors on page 100, 5 authors per page. For the first author from those five selected I want to know the first work of art authored. Here is my code and the error encountered. How this can be fixed?
irb(main):021:0* a = Author.page(100).per(5)
=> #<Kaminari::Neo4j::Paginated:0x007fde539b3c30 @source=Author(author_name: String), @current_page=100, @per_page=5>
irb(main):022:0> a.first
CYPHER 792ms MATCH (result_author:`Author`) RETURN result_author SKIP {skip_495} LIMIT {limit_5} | {:skip_495=>495, :limit_5=>5}
=> #<Author uuid: nil, author_name: "1520?, Pittoni Battista, B.">
irb(main):023:0> w = a.first.wokas.first
CYPHER 361ms MATCH (result_author:`Author`) RETURN result_author SKIP {skip_495} LIMIT {limit_5} | {:skip_495=>495, :limit_5=>5}

I realized I should provide this an an answer ;)
I think that this was fixed in version 5.0.12 of the neo4j gem. Could you update and see if that works?
