Getting 'NoneType' object has no attribute 'find' error when WebScraping with BS

[Franky77]

Hello,
please help python experts. I want to iterate through multiple pages for products info but when loop gets to the second page of products it throws me 'NoneType' object has no attribute 'find' error. Everything looks find to me though.

from urllib.request import urlopen as uReq
from urllib.request import Request
import requests
from bs4 import BeautifulSoup as soup

pagenumbers = ["1", "2", "3", "4", "5", "6", "7", "8", "9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30"]

url = "https://www.costway.ca"
first_r = requests.get(url)
first_soup = soup(first_r.content,'lxml')
allpage_urls = first_soup.find('div',{'class':'category-content shop-by-catagory'}).find_all('a')
#print(allpage_urls)
for link in allpage_urls:
    originalurl = "https://www.costway.ca" + link['href'] 
    print(originalurl)
    for page in pagenumbers:
        Cat_page_url = originalurl+"?p="+page
        print(Cat_page_url)
        third_r = requests.get(Cat_page_url)
        third_soup = soup(third_r.content,'lxml')
        names=third_soup.find('div',{'class':'pro_datu'}).find_all('a')
        for y in names:
            product_url = y['href']
            print(product_url)
            fourth_r = requests.get(product_url)
            fourth_soup = soup(fourth_r.content,'lxml')
            product_names=fourth_soup.find('div',{'class':'prod_nx'}).find('div',{'class':'orat'}).find('span').find_next_sibling('span')
            Product_number = product_names.text
            print(Product_number)
