Answer 1

You can use this:

Product.replaceOne({ _id: 55be3c8f79bae4f80c6b17f8}, {                         
   product_id: parseInt(product.id),
   parent_id: parseInt(product.parent_id),
   sku: product.sku,
   title: product.title,
   pricenormal: parseFloat(product.price_normal),
   pricewholesale: parseFloat(product.price_wholesale),
   pricewholesalelarge: parseFloat(product.price_wholesale_large),
   pricesale: parseFloat(product.price_sale),
   weight: parseFloat(product.weight),
   volume: parseFloat(product.volume),
   unittype: product.unit_type,
   status: product.status,
   datecreating: product.datecreating,
   sp: product.sp,
   guaranteeext: product.guarantee_ext,
   used: product.used,
   statusfull: product.status_full,
   description: null,
   url: null});

Answer 2

When you do new Product(), a new _id is generated, along with other things. Try this:

items.forEach(function (product) { //update or create new products

  // Es6 assign
  var productToUpdate = {};
  productToUpdate = Object.assign(productToUpdate, product._doc);
  delete productToUpdate._id;

  Product.findOneAndUpdate({product_id: product.product_id}, productToUpdate, 
                         {upsert: true}, function (err) {
    if (err)  return updateDBCallback(err);
       updateDBCallback(null, 'saved');

  });

});

try to use

const product = productEntity.toObject();
...
delete product._id;
...
Product.findOneAndUpdate({product_id: product.product_id}, product)
