Google Tag Manager / Enhanced E-commerce - Purchase tag dataLayer push working only on Tag Assistance

I'm trying to add Enhance Ecommerce but something isn't okay. When I make an order through Google Tag Assistance everything is working and the transaction is showed on the Google Analytics but when I make an order normally like customer nothing is showed.

This is what I've added to thank-you page on the shop

<script type="text/javascript">

dataLayer.push({ ecommerce: null });
dataLayer.push({
    'event': 'transaction',
    'ecommerce': {        
        'purchase': {
            'actionField': {
                'id': '<?php echo $order->get_order_number() ?>',
                'revenue': '<?php echo number_format($order->get_subtotal(), 2, ".", ""); ?>', 
                'number_of_products': '<?php echo $order->get_item_count(); ?>'
            },
            'products': [
                
                <?php foreach ($order->get_items() as $key => $item): ?>
                {
                    'name': '<?php echo $item['name']; ?>',
                    'id': '<?php echo $item['product_id']; ?>',
                    'price': '<?php echo number_format($item->get_total(), 2, ".", ""); ?>',
                    'quantity': '<?php echo $item['qty']; ?>'
                },
                <?php endforeach; 
                ?>
            ]
        }
    }
});

</script> 

And this is my setup in Google Tag Manager

tag

The trigger

Few variables - order_id

Product name

Tried google, tried tutorials and still nothing helped.

When I run from Tag Assistant everything is go to analytic. When doesn't go through Tag Assistant nothing is showed.

Any ideas?
