Scraping child pages which open in a pop-up

Describe the problem.

My start URL has a list of subpages which are all links. I've designed a scraper which accurately extracts what I want from these subpages if I start there. However if I try to get it to start on the page with all the urls for the subpages I get no data returned. I've tried different ways of getting to the sub-pages but with no success. If I do data/element preview it will load the subpage in a new window.

Url: Pubs using the FREE Real Ale Finder service and app

Sitemap:
{{"_id":"realalefinder","startUrl":["https://www.realalefinder.com/pubs/"],"selectors":[{"id":"page","parentSelectors":["pubs"],"type":"SelectorElement","selector":"div#wrapper","multiple":true,"delay":0},{"id":"cask","parentSelectors":["page"],"type":"SelectorElement","selector":"div.beernow","multiple":true,"delay":0},{"id":"beername","parentSelectors":["beergrid"],"type":"SelectorText","selector":"h1","multiple":false,"delay":0,"regex":""},{"id":"brewer","parentSelectors":["beergrid"],"type":"SelectorText","selector":"h2:nth-of-type(2)","multiple":false,"delay":0,"regex":""},{"id":"description","parentSelectors":["beergrid"],"type":"SelectorText","selector":"p","multiple":false,"delay":0,"regex":""},{"id":"pubs","parentSelectors":["_root"],"type":"SelectorPopupLink","selector":"a.publink","multiple":true,"delay":0},{"id":"beergrid","parentSelectors":["cask"],"type":"SelectorElement","selector":"div.beer-item.grid","multiple":true,"delay":0},{"id":"beerimage","parentSelectors":["beergrid"],"type":"SelectorImage","selector":"img","multiple":false,"delay":0}]}}

@sidds Hello, have you tried using the 'Link' type selector instead of a 'Pop-up'?

Example:

{"_id":"realalefinder","startUrl":["https://www.realalefinder.com/pubs/"],"selectors":[{"id":"page","multiple":true,"parentSelectors":["pubs"],"selector":"div#wrapper","type":"SelectorElement"},{"id":"cask","multiple":true,"parentSelectors":["page"],"selector":"div.beernow","type":"SelectorElement"},{"id":"beername","multiple":false,"parentSelectors":["beergrid"],"regex":"","selector":"h1","type":"SelectorText"},{"id":"brewer","multiple":false,"parentSelectors":["beergrid"],"regex":"","selector":"h2:nth-of-type(2)","type":"SelectorText"},{"id":"description","multiple":false,"parentSelectors":["beergrid"],"regex":"","selector":"p","type":"SelectorText"},{"id":"pubs","multiple":true,"parentSelectors":["_root"],"selector":"a.publink","type":"SelectorLink"},{"id":"beergrid","multiple":true,"parentSelectors":["cask"],"selector":"div.beer-item.grid","type":"SelectorElement"},{"id":"beerimage","multiple":false,"parentSelectors":["beergrid"],"selector":"img","type":"SelectorImage"}]}
