yii2 is not getting id in action after $model->save() and when I click the update item icon - yii2

Question

I have a yii2 project, I am developing on my windows localhost and hosting remotely on linux.
Locally (windows) every thing is perfect.
While on linux, I have $model->id = null after $nodel->save(), although data is saved.
public function actionCreate() {
$model = new AppBreakingNews();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
I have tried die($model->id) after the save, it printed null.
Moreover, when I click on the update icon in the grid view, I am facing the same problem.
The AppBreakingNews is as follows:
<?php
namespace app\models\appmodels;
use app\models\BreakingNews;
use yii\behaviors\TimestampBehavior;
class AppBreakingNews extends BreakingNews {
public function behaviors() {
return [
[
'class' => TimestampBehavior::className(),
'createdAtAttribute' => 'created_at',
'updatedAtAttribute' => 'updated_at',
'value' => date('Y-m-d H:i:s'),
],
];
}
}
Notice that appBreakingNews extends the model BreakingNews that is generated by yii2 without any change.
Thanks in advance..

Please try to save model->save(false); because i think it validate something from model file.
public function actionCreate() {
$model = new AppBreakingNews();
if ($model->load(Yii::$app->request->post()) && $model->save(false)) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
or can you please print your model file here.
