Retrieves an appropriate error representation in JSON.

Note: This should only be used in WP_REST_Server::serve_request(), as it cannot handle WP_Error internally. All callbacks and other internal methods should instead return a WP_Error with the data set to an array that includes a ‘status’ key, with the value being the HTTP status to send.

$code string Required

WP_Error-style code.

$message string Required

Human-readable message.

$status int Optional

HTTP status code to send.

Default: null

string JSON representation of the error
