Error codes

Error codes are Neo4j status codes returned by the server when the execution of a query fails. They always have the severity level ERROR. Errors are grouped based on the type of the error code:

Client errors: These errors are caused by the client and are usually related to the request itself. Client errors have the prefix Neo.ClientError.
Transient errors: These errors are detected by the server and are usually related to some kind of database unavailability, such as limits reached, out-of-memory, timeouts, etc. The error can be temporary and could therefore succeed if retrying the request. Transient errors have the prefix Neo.TransientError.
Database errors: These errors are caused by the database and are usually related to the database state. Database errors have the prefix Neo.DatabaseError.
