WP_REST_Server::error_to_response( WP_Error $error )
Converts an error to a response object.
Description
This iterates over all error codes and messages to change it into a flat array. This enables simpler client behaviour, as it is represented as a list in JSON rather than an object/map.
Parameters
Return
(WP_REST_Response) List of associative arrays with code and message keys.
