Code

public function getInfo() {
    // By default, we don't want Ajax commands being rendered in the context of
    // an HTML page, so we don't provide defaults for #theme or #theme_wrappers.
    // However, modules can set these properties (for example, to provide an
    // HTML debugging page that displays rather than executes Ajax commands).

        '#header' => TRUE,
        '#commands' => [],
        '#error' => NULL,
