I am unable to extract the session_id from this session info. I can extract everything else without issue. I am guessing a syntax or improper way of addressing it. Here is the session info. I want to extract the value in red. Any help is appreciated. Thank you!!!

Session: Session(Users,1,Map(gatling.http.cache.dns → io.gatling.http.resolver.ShuffleJdkNameResolver@4c975e5e, gatling.http.cache.contentCache → io.gatling.core.util.cache.Cache@581fc790, GetText → Leukemia is cancer, gatling.http.cache.redirects → io.gatling.core.util.cache.Cache@3ecdad7a, 6435007a-dbda-4948-ab81-93296f48dce0 → 1, searchCriterion → Leukemia, gatling.http.referer → https://search.nih.gov/search?utf8=✓&affiliate=nih&query=Leukemia&commit=Search, gatling.http.cookies → CookieJar(Map(CookieKey(_session_id,search.nih.gov,/) → StoredCookie(_session_id=424eda01c7a7240a02921f8fb8597435; path=/; secure; HTTPOnly,true,false,1512491440330), CookieKey(request_method,search.nih.gov,/) → StoredCookie(request_method=GET; path=/; secure,true,false,1512491440330)))),1512491435546,19,KO,List(ExitOnCompleteLoopBlock(6435007a-dbda-4948-ab81-93296f48dce0)),io.gatling.core.protocol.ProtocolComponentsRegistry$$Lambda$449/906347731@122576c8)
