Constructor Details

#initialize(id, start_node_id, end_node_id, type, properties, element_id = nil, start_node_element_id = nil, end_node_element_id = nil) ⇒ Relationship

Bolt 4.x wire doesn't include start/end_node_element_id — PackStream hydration passes nil for those slots. Fall back to the stringified node id so callers always see a value (matches what Java's driver does for 4.x). Path-bound relationships pass the actual node element_ids from #bind, which override the fallback.
