MATCH Query Syntax issues

[dianaoa22]

I have the data populated below however I cannot use MATCH query with instance-identifier.

SELECT * FROM cypher('test_graph', $$ MATCH (n) RETURN (n) $$) AS (vertex agtype);
vertex

ERROR: syntax error at or near "cluster"
LINE 1: .../universe:another-universe/globular-cluster[name='cluster-42...

If I use / to bypass the syntax error (as it allowed to populate this in DB) it doesn't match the data in DB, hence no results are returned.

SELECT * FROM cypher('test_graph', $$ MATCH (p:SL4SHuniverseC0L0NanotherDASHuniverse {id: '/universe:another-universe'}), (c:globularDASHcluster {id: '/universe:another-universe/globular-cluster[name='cluster-429']'}) CREATE (p)-[:CONTAINS]->(c) $$) AS (result agtype);
result

@dianaoa22 I think you need to look over your query and look at the usage of quotes, single and double.

Thanks it worked.
