Custom root @cypher query without arguments throws an error

[smkhalsa]

If I create a custom @cypher query on the root query type in my schema with no arguments, it throws an error. This appears to be due to the fact that without query arguments, the second field of apoc.cypher.runFirstColumn is empty.

I have the following in my schema:

type Album implements SongCollection {
  id: ID!
  name: String!
  songs: [Song!]! @cypher(statement: "MATCH (this)-[r:HAS_SONG]->(s:Song) RETURN s ORDER BY r.number")
  imageName: String  
  artists: [Artist!]! @relation(name: "BY_ARTIST", direction: "OUT")
  songRelations: [SongAlbumRelation!]!
}

type Query {
  PopularAlbums: [Album!]! @cypher(statement: "Match (a:Album) return a ORDER BY a.name")
}

If I make the this query:

query {
  PopularAlbums {
    name
  }
}

I get this error:
