Queue problem. What am I doing wrong?

Question

Yii

Good day, a question about the yiisoft / yii2-queue extension, what I'm doing wrong

$queue = \Yii::$app->queue;
        foreach ( $items as $item ) {
            $queue->push( new ImportQueue( ['data' => $item] ) );
        }
$queue->run( false );

Everything seems to be fine, the queue is being formed, it is being executed, but at the time of execution the site lies with 504. File type, Help me out
