Instagram is a tricky one and you will need some advanced tricks. Notably, the site uses a separate scroller for the popup window. You will need to use the un(der)documented "scrollElementSelector" scroller parameter to select the correct scroll element. This parameter must be added manually in the Json (it cannot be added via GUI).
Try this sitemap which will stop at 100 results. I also used a longer delay because the shorter ones seem to trigger bot detections. You can adjust the numbers as needed. Tested with Page load delay: 4500.
Sitemap:
{"_id":"instagram-followers-2023","startUrl":["https://www.instagram.com/lateinamerika_nachrichten/followers/"],"selectors":[{"id":"Username","multiple":false,"parentSelectors":["_root"],"regex":"","selector":"main header h2","type":"SelectorText"},{"delay":4222,"elementLimit":100,"id":"Separate scroller","multiple":true,"parentSelectors":["_root"],"scrollElementSelector":"div[role='dialog'] div[role='dialog'] div[style^='max-height'] > div:last-of-type","selector":"div[role=\"dialog\"] div[role=\"dialog\"] div div[style*=\"position: relative\"] > div:nth-of-type(n+4)","type":"SelectorElementScroll"},{"id":"Row wrappers","multiple":true,"parentSelectors":["_root"],"selector":"div[role=\"dialog\"] div[role=\"dialog\"] div div[style*=\"position: relative\"] > div","type":"SelectorElement"},{"id":"Handle","multiple":false,"parentSelectors":["Row wrappers"],"regex":"","selector":"a > div > div > span:first-of-type","type":"SelectorText"},{"id":"Name","multiple":false,"parentSelectors":["Row wrappers"],"regex":"","selector":"div > div > span:first-of-type > span","type":"SelectorText"},{"id":"Link","linkType":"linkFromHref","multiple":false,"parentSelectors":["Row wrappers"],"selector":"a","type":"SelectorLink"}]}
The scroller parameter I added is:
"scrollElementSelector": "div[role='dialog'] div[role='dialog'] div[style^='max-height'] > div:last-of-type",
