The format is:

+{ "error": { "class": json-string, "data": json-value, "desc": json-string },
+ "id": json-value }
Where,
- The "class" member contains the error class name (eg. "ServiceUnavailable")
- The "data" member contains specific error data and is defined in a
per-command basis, it will be an empty json-object if the error has no data
+- The "desc" member is a human-readable error message. Clients should
+ not attempt to parse this message.
- The "id" member contains the transaction identification associated with
the command execution (if issued by the Client)
