    public function check_authentication()
         * Filters REST authentication errors.
         * This is used to pass a WP_Error from an authentication method back to
         * the API.
         * Authentication methods should check first if they're being used, as
         * multiple authentication methods can be enabled on a site (cookies,
         * HTTP basic auth, OAuth). If the authentication method hooked in is
         * not actually being attempted, null should be returned to indicate
         * another authentication method should check instead. Similarly,
         * callbacks should ensure the value is `null` before checking for
         * errors.
         * A WP_Error instance can be returned if an error occurs, and this should
         * match the format used by API methods internally (that is, the `status`
         * data should be used). A callback can return `true` to indicate that
         * the authentication method was used, and it succeeded.
         * @since 4.4.0
         * @param WP_Error|null|bool WP_Error if authentication error, null if authentication
         *                              method wasn't used, true if authentication succeeded.
