Trying to crawl a web site but get an issue with Javascript

I’ve created a new search set including the URL, user and password. Search for “*”, follow links, etc, etc.
Latest versions of safari, devon, etc.
The only result I get is always this error:
“We’re sorry but this app doesn’t work properly without JavaScript enabled. Please enable it to continue.”
Any idea?

Crawling isn’t compatible to dynamic websites requiring JavaScript currently.
