I can't import data from gtm's data layer into my own database

I created a data layer in gtm and wrote a script to import the information reflected in this part into my own data store, but something seems wrong.

I have a trigger called addToCard, and with this event, my script fires as it pulls the data.

but my data block looks empty as seen in the image

Please help, I can explain more details you want. at least give me advice..

`

<script>
var SvstData={};


var a = window['dataLayer']
var x =[]
var b
a.forEach(item=>{
    if(item.event=="addToCart"){
        b=item
    }
})
if(a){
     b.ecommerce.add.products.forEach((item) = function() {

      x.push({
        pId: item.id,
          pQty: item.quantity,
          pPrice: item.price,
          pName: item.name,
        url: '0',
        pimg: '0',
        image_url: '0',
        category_name: item.category,
        category_id: '0',
        brand: item.brand,
        brand_id: '0',
        product_code: '0',
        title: item.name,
        currency: '0',
        price_sell: item.price,
        price_order_general: item.price
        })
})
SvstData.product = x
SvstData.count = x.length
SvstData.email= a[2].userinfo.email;
SvstData.oAmt= a[4].ecommerce.checkout.products[0].price;
SvstData.oID= a[4].ecommerce.checkout.products[0].id;
}

SvstData.status= "cart";

</script>
