Sometimes Image is missing, why?

How to?
#1

For first, i can not scrape all procuts with following informations:

Brand, Description(short), Price, Image

So now i want to scrape the information of of overview site.
In this method i only can grab shorten products informations names.

But i sometimes, the scrape has no image links

Url: https://www.dm.de/pflege-und-duft/koerperpflege/deo/?type=product&tenant=de_mcr&targetSystem=live&categoryId=020106&pageSize=48&sort=relevance&cp=1

Sitemap:
{"_id":"dm_deos","startUrl":["https://www.dm.de/pflege-und-duft/koerperpflege/deo/?type=product&tenant=de_mcr&targetSystem=live&categoryId=020106&pageSize=48&sort=relevance&cp=1"],"selectors":[{"id":"Container","type":"SelectorElement","parentSelectors":["_root"],"selector":"div.js-addToCart-container","multiple":true,"delay":0},{"id":"Marke","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navsb","multiple":false,"regex":"","delay":0},{"id":"Beschreibung","type":"SelectorText","parentSelectors":["Container"],"selector":".a a","multiple":false,"regex":"","delay":0},{"id":"Preis1","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navlk","multiple":false,"regex":"","delay":0},{"id":"Preis2","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navlg","multiple":false,"regex":"","delay":0},{"id":"Bild","type":"SelectorImage","parentSelectors":["Container"],"selector":"img.navwn","multiple":false,"delay":0}]}

The images only appear when they are rendered, so you will have to use Element Scroll for this one

This should work:

{"_id":"dm_deos","startUrl":["https://www.dm.de/pflege-und-duft/koerperpflege/deo/?type=product&tenant=de_mcr&targetSystem=live&categoryId=020106&pageSize=48&sort=relevance&cp=1"],"selectors":[{"id":"Container","type":"SelectorElementScroll","parentSelectors":["_root"],"selector":"div[data-dmid=\"product-tile-container\"]","multiple":true,"delay":"2000"},{"id":"Marke","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navsb","multiple":false,"regex":"","delay":0},{"id":"Beschreibung","type":"SelectorText","parentSelectors":["Container"],"selector":".a a","multiple":false,"regex":"","delay":0},{"id":"Preis1","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navlk","multiple":false,"regex":"","delay":0},{"id":"Preis2","type":"SelectorText","parentSelectors":["Container"],"selector":"span.navlg","multiple":false,"regex":"","delay":0},{"id":"Bild","type":"SelectorImage","parentSelectors":["Container"],"selector":"img","multiple":false,"delay":0}]}
