                        // be handled by the built in PHP error handler.

                        throw new \ErrorException($message, 0, $level, $file, $line);
                    }

            }

    }

    /**

In your ajax scenario, maybe return with one of these?

if (wp_doing_ajax()) {
    ...
    wp_send_json( $response:mixed, $status_code:integer|null, $options:integer )
    wp_send_json_error( $data:mixed|null, $status_code:integer|null, $options:integer )
    ...
}

Docs: wp_send_json
Docs: wp_send_json_error

Works like a charm Mike... even with Ajax requests without using wp_send_json or wp_send_json_error.

Thank you again ;D
