Nebula Graph (nGQL) Cypher not returning values in jupyter

59 views Asked by At

Trying to run a Nebula Graph Query Cypher from the excellent tutorial by Wenqi Glantz: https://www.nebula-graph.io/posts/Knowledge-Graph-and-LlamaIndex

%%ngql 
MATCH (p:`entity`)-[e:relationship]->(m:`entity`)
  WHERE p.`entity`.`name` == 'Philadelphia Phillies'
RETURN p, e, m;

Doing so returns no values for p,e,m.

Running the same request using plain text/sentences using the query engine returns an appropriate answer just fine.

Unsure why the ngql query cypher is failing to yield results. Thanks for your help.
