Появляется ошибка, не понимаю как её исправить Setting unknown property: yii\bootstrap5\ActiveForm::model?

Я удалила, теперь появилась другая ошибка: Call to a member function hasErrors() on null
in C:\OSPanel\domains\basic\vendor\yiisoft\yii2\widgets\ActiveField.phpat line 964

protected function addErrorClassIfNeeded(&$options)
{
// Get proper attribute name when attribute name is tabular.
$attributeName = Html::getAttributeName($this->attribute);

if ($this->model->hasErrors($attributeName)) {
Html::addCssClass($options, $this->form->errorCssClass);
}
}
}
