Conquering Neo4j Errors: GQLSTATUS Codes to the Rescue
summary
Neo4j replaces brittle text parsing with a structured GQL status system that provides a stable 5‑character code plus human descriptions, diagnostics, and optional causes; demos show the Java driver using E.containsEqualStatus with codes like 22N77 and query-log JSON containing errorInfo; an error migration tool maps legacy messages to codes; new docs list individual-code scenarios and solutions; success and notification codes (e.g. 0000001, z1 warnings) appear and the demos work as advertised.
