ArgumentCountError in Yii 2

I have created 3 course contents. But unfortunately, it only shows 1 course content as what the picture showed below. What I am trying to do is to show ALL the course content that I created earlier. It runs normal when I run with this syntax.

public function actionView($id)
    {
        $dataProvider = new ActiveDataProvider([
            'query' => Coursecontent::findAll()->andFilterWhere(['coursecontent_id' => $id]),
        ]);

        return $this->render('view', [
            'model' => $this->findModel($id), 'dataProvider' => $dataProvider,
        ]);
    }

enter image description here

But when I changed my code to this. It shows this error message. What i am trying to do here is to show all the course contents. Too few arguments to function yii\db\BaseActiveRecord::findAll(), 0 passed in D:\XAMPP\htdocs\valuefarm\algobox_admin\controllers\CourseController.php on line 57 and exactly 1 expected

public function actionView($id)
    {
        $dataProvider = new ActiveDataProvider([
            'query' => Coursecontent::findAll()->andFilterWhere(['coursecontent_id' => $id]),
        ]);

        return $this->render('view', [
            'model' => $this->findModel($id), 'dataProvider' => $dataProvider,
        ]);
    }

You don't need to fetch the data for ActiveDataProvider, it will do it for you.

Just provide the query.

public function actionView($id)
{
    $dataProvider = new ActiveDataProvider([
        'query' => Coursecontent::find()->andFilterWhere(['coursecontent_id' => $id]),
    ]);

    return $this->render('view', [
        'model' => $this->findModel($id), 'dataProvider' => $dataProvider,
    ]);
}

Your error is findAll() expects a condition and will return results, not an ActiveQuery instance.

e.g.

Coursecontent::findAll(['coursecontent_id' => $id]);
