Unable to scrape items using scrapy

I am trying to webscrape the name, price, and description of products listed on an online shop. The website link is https://eshop.nomin.mn/n-foods.html

When I look through the HTML code of the page, I get the relevant div class containers but when I reference it in my code as such, I get no values when I run my spider. I think one reason would be if the website is Javascript based and is dynamic which would require me to use Splash. However, I don't think this is the case for my issue.

def parse(self, response, **kwargs):
    cards = response.xpath('//div[@class="item-itemmainroot-1lZ"]')

    # parse details
    for card in cards:
        price = card.xpath(".//a[contains(@class, 'item-nameLenght-K5Z item-name-3TH')]/span()/text()").extract()

Full Code:

import scrapy
import re


class TempSpider(scrapy.Spider):
    name = 'temp_spider'
    allowed_domains = ['https://eshop.nomin.mn/']
    start_urls = ['https://eshop.nomin.mn/n-foods.html']

    def parse(self, response, **kwargs):
        cards = response.xpath('//div[@class="item-itemmainroot-1lZ"]')

        # parse details
        for card in cards:
            price = card.xpath(".//a[contains(@class, 'item-nameLenght-K5Z item-name-3TH')]/span()/text()").extract()
            
            item = {'price': price
                    }
            yield item

All and any help is greatly appreciated. I can't seem to figure out what I am doing wrong.

Use the websites data api instead of the website url that you visit in your browser. It will return a json object that has all the information you are looking for.

import scrapy
import re


class TempSpider(scrapy.Spider):
    name = 'temp_spider'
    allowed_domains = ['https://eshop.nomin.mn/']
    start_urls = ['https://eshop.nomin.mn/graphql?query=query+category($pageSize:Int!$currentPage:Int!$filters:ProductAttributeFilterInput!$sort:ProductAttributeSortInput){products(pageSize:$pageSize+currentPage:$currentPage+filter:$filters+sort:$sort){items{id+name+sku+brand+salable_qty+brand_name+c21_available+c21_business_type+c21_reference+c21_street+c21_area+c21_bed_room+mp_daily_deal{created_at+date_from+date_to+deal_id+deal_price+remaining_time+deal_qty+discount_label+is_featured+product_id+product_name+product_sku+sale_qty+status+store_ids+updated_at+__typename}new_to_date+short_description{html+__typename}productAttributes{name+value+__typename}price{regularPrice{amount{currency+value+__typename}__typename}__typename}special_price+special_to_date+thumbnail{file_small+url+__typename}url_key+url_suffix+mp_label_data{enabled+name+priority+label_template+label_image+to_date+__typename}...on+ConfigurableProduct{variants{product{sku+special_price+price{regularPrice{amount{currency+value+__typename}__typename}__typename}__typename}__typename}__typename}__typename}page_info{total_pages+__typename}total_count+__typename}}&operationName=category&variables={"currentPage":1,"id":24175,"filters":{"category_id":{"in":"24175"}},"pageSize":50,"sort":{"position":"DESC"}}']

    def parse(self, response, **kwargs):
        data = response.json()
        print(data.keys())
        for item in data['data']["products"]["items"]:
            yield {
                "name": item["name"],
                "price": item["price"]["regularPrice"]["amount"]["value"]
            }
