Are there any common guides/standards for returning error messages from network-based APIs (REST, RESTful, RPC...), perhaps some kind of generic schemas? I am aware of RFC-7807 [0], but it seems overly complicated and essentially requires keeping a database of common error types (which admittedly _is_ useful, but usually an overkill).
