Javascript ,scrapes only the first result

Hi there
Hope your great
I am struggling to scrape data from dynamic sites like this one.With this sitemap i only scrape the first result and i cant continue.Can someone explain for future project how can i manage the scraper ?
Thank you

Url: Feriavalencia Catalog

Sitemap:
{"_id":"cevisama","startUrl":["Feriavalencia Catalog div.col-10","multiple":false,"regex":"","delay":0}]}

I can only do that for you. Hope It'll help.
You gonna see some empty pages but don't worry I hope you will find 95%-99% of your data.
