The method options() does not exist on Yiisoft\Widget\Widget. It seems like you code against a sub-type of Yiisoft\Widget\Widget such as Yiisoft\Form\Widget\Form or Yiisoft\Yii\Bootstrap5\Nav or Yiisoft\Yii\Bootstrap5\Button or Yiisoft\Yii\Bootstrap5\Carousel or Yiisoft\Yii\Bootstrap5\Progress or Yiisoft\Yii\Bootstrap5\Dropdown or Yiisoft\Yii\Bootstrap5\Toast or Yiisoft\Yii\Bootstrap5\ButtonDropdown or Yiisoft\Yii\Bootstrap5\Tabs or App\Blog\Widget\PostCard or Yiisoft\Yii\Bootstrap5\Accordion or Yiisoft\Yii\Bootstrap5\Breadcrumbs or App\Widget\OffsetPagination or Yiisoft\Yii\Bootstrap5\Modal or Yiisoft\Yii\Bootstrap5\Alert or Yiisoft\Yii\Bootstrap5\NavBar or Yiisoft\Yii\Bootstrap5\ButtonToolbar or Yiisoft\Yii\Bootstrap5\ButtonGroup.

                    ->body($message['body'])
                ;
            }
        }

        return implode($html);
    }
