Please help with sitemap

Hi, I am trying to scrape a website, but are getting blank spaces.

{"_id":"happy_healthcare","startUrl":["https://happyhealthcare.shop/collections/oncologia"],"selectors":[{"id":"Producto","type":"SelectorText","parentSelectors":["_root"],"selector":"div.grid-item:nth-of-type(n+5) p","multiple":true,"regex":"","delay":0},{"id":"precio","type":"SelectorText","parentSelectors":["_root"],"selector":"div.grid-item:nth-of-type(n+5) small","multiple":true,"regex":"","delay":0},{"id":"next","type":"SelectorElementClick","parentSelectors":["next"],"selector":"ul.pagination-custom li:nth-of-type(3) a","multiple":true,"delay":0,"clickElementSelector":"ul.pagination-custom li:nth-of-type(3) a","clickType":"clickOnce","discardInitialElements":false,"clickElementUniquenessType":"uniqueText"}]}

I would apreciate if anyone can help me!
