Defined in:

Overview

Bolt 5.7. FAILURE switches to a GQL-flavoured map: the legacy code key is renamed to neo4j_code (optional, defaults to "N/A"), and new keys appear (gql_status, description, diagnostic_record, recursive cause). The driver's exception classifier keys off :code, so we alias neo4j_code → code here. The other GQL fields ride along in the metadata for any caller that wants them.

5.7+ is also where HandshakeManifestV1 negotiation becomes mandatory on the server side; that's handled in Bolt::Handshake, not here.
