WITH RECURSIVE Not Working Correctly - Postgres

Question

I have two tables representing a graph. Nodes consists of an id, type and properties. Edges consist of an id, properties, type and an origin node id and destination node id. I've been working on a query that will basically take a single node and return the graph to a given depth - heavily based (basically copied) on an article here - https://www.alibabacloud.com/blog/postgresql-graph-search-practices---10-billion-scale-graph-with-millisecond-response_595039

However, whenever I run the query my results are always returned with many duplicates of the first query, as if it's not running running the recursive part - I'm not sure what I'm doing wrong here.

Here is my query.

WITH RECURSIVE search_graph(
  id,   
  origin_id,-- point 1     
  origin_metatype_id,
  origin_properties,    
  destination_id,   -- point 2
  destination_metatype_id,
  destination_properties,
  relationship_pair_id, 
  properties, -- edge property      
  depth, -- depth, starting from 1      
  path  -- path, stored using an array      
) AS (      
        SELECT    -- ROOT node query 
          g.id, 
          g.origin_id,-- point 1      
          n1.metatype_id AS origin_metatype_id,
          n1.properties AS origin_properties,
          g.destination_id,   -- point 2   
          n2.metatype_id AS destination_metatype_id,
          n2.properties AS destination_properties,
          g.relationship_pair_id,
          g.properties,   -- edge property      
          1 as depth,        -- initial depth =1      
          ARRAY[g.id] as path  -- initial path         
        FROM current_edges AS g
            LEFT JOIN nodes n1 ON n1.id = g.origin_id
            LEFT JOIN nodes n2 ON n2.id = g.destination_id
        WHERE       
          origin_id = ?        -- ROOT node =?      
      UNION ALL    
        SELECT 
          g.id,-- recursive clause      
          g.origin_id,-- point 1      
          n1.metatype_id AS origin_metatype_id,
          n1.properties AS origin_properties,
          g.destination_id,   -- point 2   
          n2.metatype_id AS destination_metatype_id,
          n2.properties AS destination_properties,
          g.relationship_pair_id,
          g.properties,          -- edge property      
          sg.depth + 1 as depth,    -- depth + 1      
          sg.path || g.id as path   -- add a new point to the path      
        FROM current_edges AS g     
            LEFT JOIN nodes n1 ON n1.id = g.origin_id
            LEFT JOIN nodes n2 ON n2.id = g.destination_id,
        search_graph AS sg   -- circular INNER JOIN    
        WHERE                 
          g.origin_id = sg.destination_id        -- recursive JOIN condition      
          AND (g.id != ALL(sg.path))        -- prevent from cycling      
          AND sg.depth <= 10    -- search depth =?         
)      
SELECT * FROM search_graph;
