Yii 2 error - Trying to get a property of non object

Question

I was trying to search the needed information, but couldn't find any of that. Somehow, I get this error and I don't know where I'm doing a mistake.

Here is my action:

public function actionFilter()
{
    $filterParams = Yii::$app->request->get();
    unset($filterParams['r']);

    $model = new Sale();
    $dataProvider = $model->filterParameters($filterParams);

    return $this->render('filter', [
        'dataProvider' => $dataProvider,
        'filterParams' => $filterParams,
    ]);
}

And here is my view:

'attribute' => 'sale_id',
'width' => '14%',
'value' => function (Sale $model) {
    return $model->sale->client->getClientName();
}
],  
[
    'attribute' => '',
    'value' => function (Sale $model) {
        return $model->sale->client->getClientSale();
    }
],

I'm getting the error on the 'value' return line. The function getClientName() is in client model. Could someone explain what I'm doing wrong? Thanks for any help.

Propably there's no model linked to your main $model. You should check if it's set by:

return $model->debtor && $model->debtor->client ? $model->debtor->client->getFullName() : null;

AND

 return $model->debtor && $model->debtor->user ? $model->debtor->user->getFullName() : null;
