ConstraintValidationFailed error does not show when cypher error

Neo4j Graph Platform Server
1

Not sure what happen, but now my server does not show the detail error when cypher error:
Ex:

CREATE (charlie:Person:Actor {name: 'Charlie Sheen'})-[:ACTED_IN {role: 'Bud Fox'}]->(wallStreet:Movie {title: 'Wall Street'})<-[:DIRECTED]-(oliver:Person:Director {name: 'Oliver Stone'})

If I do cypher

MATCH(n:Person  {name: 'Charlie Sheen'})
DELETE n

Current

#### Neo.DatabaseError.Database.Unknown

Unable to complete transaction.

Should be

Neo.ClientError.Schema.ConstraintValidationFailed

Cannot delete node<7922>, because it still has relationships. To delete this node, you must first delete its relationships.

Any idea why?

@abccbaandy

Is there any detail on Neo4j version?
At the time of error anything written to logs\debug.log?

3

version is 5.26

For debug.log, yes it write the real error about relationships exist issue.

I am unable to reproduce, for example

neo4j@ubuntu22dockerdebjava17:~/single/instance1/neo4j-enterprise-5.26.0/bin$ ./cypher-shell

Note that Cypher queries must end with a semicolon.

Cannot delete node<130000>, because it still has relationships. To delete this node, you must first delete its relationships.

through what client are you issuing the cypher statements through?

I use neo4j browser.
It's normal at beginning, and not sure when it's broken.

And I can't reproduce too, a fresh server work well, just that one fail.
